...no it isn't.
 
Do I have different ears than anyone else or are they going nuts because of the nostalgia factor?
 
I admit SOME of the songs are good (White Land isn't bad, Luigi's Mansion theme is excellent, some of the Kirby ones are good) but majority of it is pretty mediocre. And some of the songs are outright terrible.
 
But eh, there's 'tards screaming about how some of it "is MIDI" therefore it's crap..while some of the remixed songs in the game sounded better on the SNES anyway.
