Amazon has a promotion of 25 day of free holiday music. For 25 days counting down to Christmas, you can download free quality mp3s from their music site. Free tunes so far have been from Lady Gaga to Tori Amos.

Music videos on TV are hard to come by these days because they are either on early or late. However check out Vevo to watch video from the hottest artists like Lady Gaga, Jay-Z. You can even build playlists so you stop back later.
After using the site a few times, I have noticed that it takes a while for it to load. I also noticed that searches don’t seem to work correctly. However all in all, Vevo delivers on videos, so check it out.
