Will facebook ever become a good music playlist site?

with all the news i'm hearing about myspace, i fear myspce will become extinct. problem is, i really enjoy myspace because of all the music found on there. there's quite a few country songs i listen to that can only be found on myspace. i know you can like the gigya page on facebook and post playlists from sites like grooveshark and playlist.com to your facebook profile, but grooveshark and playlist especially arent the same and arent as good
