London Music Mapp
If all the Olympics excitement gets too much, perhaps you'll want to take your interests elsewhere. After all, London is probably better known for its music heritage than its sporting prowess.
London Music Mapp's creator promises it will help you do just that by showing you "new locations you never knew existed, where legendary artists once lived and played, or where great albums were recorded and the music played live for the first time".
It'll also give you details of places and streets referenced in songs, as well as listings for London's concert halls, clubs and other live venues.
