There are so many things wrong with this both conceptually and realistically.

Things like Pandora make it an automatic "no" from me. Plus, considering the age gaps, cultural differences, etc. on d2jsp there would be such a variance in music--nobody would be happy (as if they are happy ever

). I personally don't want to listen to Justin Bieber as the only "artist" on there because 50% of d2jsp is 14 years old.
