Founder Chris Chen says that its emphasis on song tracking is what separates the Like.fm from streaming services like Last.fm and music buying networks like Apple’s Ping (which he describes as “a step above adding share buttons to the iTunes store.”) says Chen “Like.fm isn’t meant to be a destination music site, it’s meant to be a place to find songs that you like. It’s not meant to be a Pandora but a compliment to it, it’s a place for sound discovery, where you go and listen to music.” It sounds to me like he's describing Last.FM perfectly. Last.FM is a social network for finding new music based on the songs you play/scrobble. I think with Pandora and Last.FM already well established and Grooveshark certainly doing fine I struggle to see the room in this market and what Like.fm provides that's different. Even the name sounds like a rip off of last.fm. Maybe there is something here that the others don't/can't provide, but I'm not seeing it - anyone have any ideas?
