My City vs. Your City
by Michael Schieben
Yesterday RyanAir changed my plans. Today I changed my plans, too. I did not feel fit enough to start building my SoundCloud / Echonest comment based remix machine and hacked around, but did nothing real this morning. After reading about the new Metreo Charts in last.fm‘s API I finally build “My City vs. Your City“.
“My City vs. Your City is a JavaScript based app that compares to what artists people listen to in different cities.
What I observed: Hamburg is closer to Munich than to Berlin or Bremen
Plans for improvement:
- Compare more than two cities
- Compare more than 10 artists
- Multiply color (to get green) for intersection of circles
- Compare different times (Hamburg is 60 % of New York 5 weeks ago)
Do you have any other ideas?
Update: I use data by last.fm to create the charts. At the time of building last.fm only offers data for the 100 cities listed on the website. I’m sorry, but cannot add more cities.
Cool! I think multiplication of the circle intersection will help a lot – I was a bit irritated at the first glance (did not expect meaning behind the blinking
I think it would also be nice to show the number behind artist names on default. Could also help to grasp the weighting better …
Neat hack! One note, I tried tweeting the urls and they didn’t make it through twitter or a url shortener unscathed. Perhaps the ‘#’ is confusing things?

@Christophe NOT doing the intersection for the first release was very confusing. That’s the first thing I changed today. I also have to rethink the titel, as it is more “What people listen to in my city AND your city”…
Now the number behing the artist name (which is total listeners from that city) is displayed all the time.
@Paul I wish I could do that better. But having hash urls is the only way to update the url while not reloading the page.
This is so cool! The most similar cities to Vienna are Southampton, Leeds. Liverpool and Edinburgh. Would like to see a list of the most similar cities (also the most dissimilar).
Where is Phoenix (Arizona, United States)? It’s the 12th-biggest metro in the U.S. (the city proper has over 1 million people) and there are much smaller cities included on this list.
@Clemens A list is a good idea as I failed doing another visualization that groups similar cities.
@Alex last.fm only charts the 100 cities listed. I have no chance to add more cities, yet.
Why, when I compare Coimbra, Portugal and Salvador, Brazil…
http://rockitbaby.de/projects/mycityvsyourcity/#coimbra/portugal/salvador/brazil
…does it tell me they have 52% in common, when only two artists (Coldplay and The Beatles) actually appear on both lists? Shouldn’t that mean they have 20% in common?
@Momus your damn right. Thanks for pointing me to a bug in the comparison algorithm!
Combria and Salvador have 14% in common. (Would be 20% if The Beatles and Coldplay where on the same chart-position in each city)
There’s a spot missing from the Houston, TX list. Thanks for your work!
Washington, DC doesn’t work :’(
Dallas, Texas USA is not on the list. 8th largest metropolitan area in the USA.
hey, I dig your site! Just so you know, “What people listen in My City vs. Your City” should say “What people listen to in My City vs. Your City… I’m an editor at heart
Where is Buenos Aires??? South America is really underrepresented, it’s a major metropolis and Brazilian data is really different.
What about Mumbai or Calcutta or Delhi? South Asia’s totally going unaccounted here.
many thanks to my editor at heart, thanks @MH.
@brad @jetsetter7 @K Sorry for not having more cities on the site: last.fm only charts the 100 cities listed. I have no chance to add more data, yet.
It would be cool to be able to look up by artist. I hate living in a city where Lady Gaga is #1 and would like to find a city where Arcade Fire or Vampire Weekend is #1.
This is so great but you need to add Melbourne, Australia!
Washington DC is busted.
where do you generate your data from?
I’d love to see this as a Me vs. Your City, so that I could see how well I line up with major cities. Plus an option to find a city that most closely matches my taste.
Instead of a drop down list, maybe you can utilize Google Map for city name. Asian cities are hugely missing from your list.
Good idea, but there is not Buenos Aires in the lists…
You forgot the 5th largesr city in the US, by population, Phoenix Arizona

@brian data is from last.fm check out the API website http://last.fm/api/show/?service=421
@TVarmy great idea. I’ll add this in the next version.
why nothing from Seoul, South Korea?
there’s hong kong, and a pretty wide swath of cities from china and japan, but nothing from Korea?
what gives?
Great idea ! Where is the tab I can share … ? When I paste the link no picture in Facebook
Why is there no data for Rio de Janeiro or São Paulo (Brazil)? Thanks!
Thanks, Michael! My theories vs. Your data:

Aww…. there’s no Perth, Australia.
Are we that insignificant!?
Were’s Brisbane, Australia? It’s the capital of one of the states in Australia which means it’s important, so why isn’t it there?
soooo…does st. louis not have people that listen to music? I tried it and I didn’t get anything from it at all…..
Cool site! Any limitations on whether Pandora can be added?
BTW Hong Kong doesn’t seem to work.
good one! UTF-8 support is dead – special/accented characters don’t work unfortunately and you get blank results for the cities with them in the names.
T!
Hi,
First off, nice app. Kudos!
It would be nice if a person could create their own top 10 list of artists ( and then compare it to the lists from various cities.
Which way of mapping did you try? By similarity, where similar cities attract each other (fascinating, but also complicated) or more simple: each city keeps its location on a map and similarity is reflected by color (or by height)?
This is a great little app! The results are coming in a bit slow for me, but then again I’m in the Philippines so there could be soo many reasons for that. I’ve just spent the last 15 mins or so comparing cities. I agree with some other responses, you should add a ‘Share on Facebook” link. This would really take off!
It would be interesting to know the city that most matches the one I select as MyCity
cool …
I am surprised there is no listing of any cities in India
Rio de Janeiro, Brazil information is empty, don’t know why.
Very interesting. I’d love to see Sheffield, UK on there as it traditionally has a very particular music scene e.g. Human League, Cabaret Voltaire, Autechre and Pulp among others. Curious to see if that’s reflected on last FM.
