Yahoo LAUNCHcast offers a personal online radio station. You can’t completely control the music that is played on your station; but you can influence the selections by rating artists, albums, and songs. The more you rate, the more selections are played that you like.

Here’s my station’s description:

NurseHealer blends contemporary pop with classic & christian rock, jazz, R&B, and top hits for an awesome mix of pleasant listening music, toe-tapping favorites, and the stuff you just can’t sit still to. Sing along or dance your shoes off! Relax to sounds for meditation or Psalms. An awesome mix!
