I just found out about Rockabye Baby lullaby renditions. There are pretty badass "covers," lullaby style, to some damn good artists. Man I hate that I didn't know about these a few years ago.
Got almost all of them for nap time at the school. Beats the crap out of all the talking/fundraising etc on the classical station, besides there's nothing like napping to AC/DC.
and FYI if you need baby shower gifts these are awesome and cheap and useful! not like the typical "You think I'm cute, You should see my... (uncle/aunt/grandma/etc)" bibs/onesie/diaper bag/blanket/pacifier/bacon/bottle warmer/wipe warmer/beer warmer/etc...
