Nathan,
Vocal sounds better now, but still a bit muffled. It sounds a bit like you recorded it with a mic out of the TV speaker. I would have thought you could have ripped it from DVD.
Some of the samples are a bit jumpy/clicky where you've cut & paste, particularly obvious around the 2 min mark where you do the breakdown.
I would have finished it at the 3min 10/13 sec mark (where you did last time?). Novelty songs are better short IMHO.
Other than that, nice one!

If it were going to be released you'd have to clean it up a bit more.
Kev.
