h found these songs on youtube (or somewhere) where they are "lullaby" versions of "today's" music...
here's a few examples, i'm still exploring on youtube, i'm sure there's tons out there..

also, i'm too lazy to do it right now, but check out "vitamin string quartet". they do "classical" style music of today's music....good for baby music that doesn't get too boring. they do tons and tons and tons of groups..but most notably, check out their lady gaga collection.
