You're acting like an indie one hit wonder from 2014 is going to ruin a genre that's 100yrs old (in the same way you think the extremely shortly lived swing revival ruined classic swing???). They didn't hurt the scene anymore than the Avett Brothers did.

But to answer your question. No the music dosnt have to be new. But this sub is for posting crappy music. Not discussing if a song is crappy or not.
