usually i'd bring up something about ocremix with a album like this but there hasn't been much new from them for a while now (now that i think of it, i wonder what the next album will be about) and i happened across this a few nights ago and its got some real nice tracks to it.

track 16. A K.Rool Pub Crawl (an excellent version of the final boss tracks of DKC sounding less like game music than an actual song)
another good one would be a track based on the Mother games, track 73. M.U.T.H.E.R.F.U.o.O.E.R (good track and it features that song used in the final boss fight of Mother 2 i think) to name a few.

now to see what this expansion to the album titled Final Smash is like.
