Reply to Candidate for a Remix

Hello all,

So I'm sitting here on Grooveshark at work, listening to some pretty sweet tunes (most of them being solid productions).

While I'm listening, I'm believeing some of these tracks could really use some UMPH!

My question is, what makes a good candidate for a remix? Can anything be remixed? If it's a heavily produced track, is it impossible?
