The Stockholm Music Hack Day hacks are starting to roll in. One really neat one is ‘hackKey‘ by Matt Ogle from Last.fm. This hack looks gives you a chart that shows you the keys of your most listened to songs in your last.fm profile:
As you can see my favorite key is E minor. I should put this on a tee-shirt.
The hack uses Brian’s new search_tracks API for the key identification. Cool beans! Will we see flaneur in velour?
I don’t know how well Matt’s hack will scale so I won’t put a link to it here on the blog until after he’s done demoing it at the hack day. Matt’s demo is done so here’s the link: http://users.last.fm/~matt/hackey/
