I don't know much about kid's music, but I do know that Over The Rhine's awesome song, The Poopsmith, was awesome when I first heard it--in 2004.
So congratulations to the overnight success of this Ohioan music phenomenon for being named one of the top 10 kid's music CD's of 2007 by the kid music experts at WXPN, Philadelphia. [npr.org via somewhere, I forget]
