We all like to share our music and show off our tastes to be a bit better than our friends. However, whereas a reference to that new band you love who only play basement gigs means nothing in conversation, Blip.fm allows you to link followers to their new demo. You decide what songs to post, and they appear as blips (essentially, posts with a song and a tweet together) on your Twitter feed, so followers can sample your tips. What I like about the service is the comprehensiveness of the database — I found eight of the 10 songs I searched for, three of which were by friends’ unsigned bands. Of course it’s not just oh-so-indie bands whom you can find; a quick search also yields hundreds of results for U2, Rihanna and Flo Rida, if that’s your preference. Yes, social networking and music have come together fruitfully before, but it has never felt this comprehensive.
