Remixes: real music or a cheap way to get attention?

I love Kap Slap's Spring Break Mix, though that was more of a mashup than a remix.

I love this remix of Kid Cudi's Pursuit of Happiness though:

And yeah, Bacon loves rap. Suck it.

Edit: Dumbfoundead's remix of Houses: Soak It Up, which was remixed by Cassettes Wont Listen is pretty tight too:
