Mash-ups, love 'em or hate 'em?

[HTA!]

I've been exploring the world of mash-ups a a little bit, and found this.

Blew me away.
Anyway, do you like listening to the fusion of two songs?
Both of the above two songs are good separate, but I loved this mixture.

Since I love MADs from Nico Nico Douga, I must say, I do love mashups.

They just have to work.  Mashups for the sake of mashing two of your favorite songs together isn't acceptable.  They have to be harmonious.
