MyStrands

Via the Macromedia XML Blog Aggregator or whatever it's called - and Adobe hasn't chaged the name there yet either, I will probably check this out:

iTunes or Windows Media Player (what, no WinAmp?)

MyStrands recommends songs based on the song actively playing in your media player, as well as recently played songs. You can listen to a recommended song directly from MyStrands with a single click, or read about the song and the artist on their MusicStrands.com home page.

It's not the first thing that's done this, but those sucked. Maybe this will too, won't know till I try. This is cool too:

Publish Playlists
Publish your favorite playlists to MusicStrands, to share with the community. You can tag and publish your active playlist by clicking the edit button next to the playlist tags. When you tag a playlist, the playlist is uploaded to the website and published.

Tag songs
You can add/edit tags to your active song by clicking the edit button. When you add a tag, the tag is also added to the MusicStrands community, letting others explore and discover the music you've added.

however, I still like audioscrobbler/last.fm:
