Whoa. Hold up a sec here.
The reason you don't like this music is because it doesn't sound like music from old PM games? That's a bit bias, if you ask me,
well, that but there's stuff that i couldn' be sure because youtube might screw it up...it really sounded like it was.
The main problem I noticed was the instruments balance, it's just weird. There's like a track in front and a background track but the background track is almost impossible to hear which shouldn't be a problem. Now the thing is, it was from youtube, so that might have explained the thing. However because of the smash music, I;m almost convinced it wasn't youtube because the youtube quality of the Paper Mario medley still sounded a bit decent (but I still noticed loss).
Thought the originl music did sounded bad. I realised that ssb rebalanced the instruments so that they are much better.
But the thing is, the ssb music was int he end fitting the sound design of the first 3 games, though, it's less pushed, it is kinda matching. I realy loved the ssb version because it made the music way better.
This is the main thing, it was more complicated, but in the end, it's really why I said that.
