Soren Johannessen posted a map to Google Maps Mania called Copenhagen Music. Basically Soren took songs from YouTube that were about Copenhagen and mapped them.
I thought this was such a great idea that I decided to create my own Music Map. My map concentrates on the UK and the US and ranges from Electric Avenue by Eddie Grant (London) to Basin Street Blues by Louis Armstrong (New Orleans).
If you can think of any songs I've missed you can even add them to the map. For the bare faced cheek of stealing his idea I've given Soren access to the database of songs I've created for the map.
