I’ve toyed with moving my MP3 collection (>1,400 files – it’s not a complete copy of my CD’s) online before, but have never really come across the right application to do it in. I messed around with Jinzora but it was surprisingly complex, brittle, and underpowered for what I was looking for.

Serendipitously, however, I recently ran across Grooveshark, and I’ve kinda fallen in love with it. Their business model seems really interesting, and most labels have bought into the concept. I like the fact that I can have the songs I want to listen to, at my fingertips, all the time. If I want to buy a song that I don’t own, I’m shot off to Amazon or iTunes – I think they had an option to buy or download tracks directly from them at some point, but have gotten rid of it since. Or maybe that’s a ‘VIP’ option – I don’t know, because I’m a free user.

The other very cool thing about the service is the ability to share playlists, for free, with other people. I can even present songs in a widget (check the right sidebar) – again, for free. Very cool. And if I’m willing to pay the $3/mo (or $30/year) for their paid service, I can even access my library on my Blackberry. iPhone service is coming shortly.

Grooveshark sounds like Spotify, except that it’s available NOW in the States.
