Well, this could be quite a long list, as can be seen by the menu list itself. To keep it brief, I will just link to some other pages:
Audioscrobbler is an interesting site that develops a program that enables its' users to display on their user page what songs were played through Winamp. You can see my AudioScrobbler User Page for yourself. I used to live for music, but these days, I love the past more than the future, and have a learned taste for what is good, and what is not.
Other interesting music site, with album lists, lyrics, and user comments, at Lyrically2.
