Check out what they've done over at Last.fm. They have a whole new interface and LOTS of new features.
They also have something new called Recommendation Radio. Last.fm has always provided recommendations based on the music that you listen to and the social network it has built, and you've always been able to preview those songs in that recommended list. However, now you can actually play a radio station that is built entirely with recommendations.
NOT ONLY THAT but you can customize that radio station. It gives you a bunch of check boxes showing all of the artists that will be played on that station. Select the ones you want. Unselect the ones you don't.
AND you can set your level of obscurity. Want to hear popular artists? Set the obscurity filter to "popular." Want to hear something new? Set the obscurity filter to "obscure."
It's pretty cool. I love that Pandora and Last.fm exist. They both have their own pros and cons. They complement each other, really, and now I feel like they're competing, so they're each getting better. It's FANTASTIC.
ON AN UNRELATED NOTE, I notice that the newest version of Limewire will automatically augment files with a number if you have another download of the same name. That feature should have been there a long time ago.
I'm excited. Yay music.
