Last FM (www.last.fm) is awesome, and has been for years. I was just considering how MuxTape (www.muxtape.com) integrates with it, and if it would do anything cool with my Loved Tracks. But looking around I see they’ve gone one better / in a different direction. They now offer podcasts! How completely awesome is that?!? So with this and the podcasts from Solid Steel (www.ninajune.net) my music tastes are almost completely catered for.
May the world bestow its bounties upon you, LastFM, internet, musicians!
