Musick8.com is the site for Plank Road Publishing.  I get all my music from this company because they give very liberal permissions with their copyright.  Students can search songs and play them online.  Not the whole song, but good chunks of them.

Animusic.com is the site for purchasing Animusic & Animusic 2.  These are invented computer generated instruments that are animated to music.  You may have had your kids talking up a strom about these videos.  If you search the net, you will be able to find some of the links to the full version of "Pipe Dreams" which was a huge internet hoax.  This a really a great way for kids to see what plays the sounds that they hear.  You can talk about tembre, small/short=high pitch and long/big=low pitch.  Great videos on the design process as well.  Personally, I wouldn't buy them unless the $ is no big deal.
