Just listened to the preview... Here's my opinions as someone who has no knowledge of music whatsoever:
I can't tell what the first track is D: I kind of heard Lost World Anthem in there but I can't really tell. Excellent drum work in the first half of the segment.
2:21, is this Snakey Chantey? This sounds like an alright track, but the style doesn't fit with the original at all in my opinion. It's way too mellow for such an upbeat source. Maybe it picks up more in the actual track.
Jib Jig is good stuff, I love this style of music
3:21? What's the source here?
Krook's March was EXACTLY like I'd hoped it would be! Definitely my favorite track of the preview. Oh man, I really, REALLY can't wait to hear this song.
Run, Rambi Run isn't my favorite style of music, but it's growing on me so I'll give Zyko the benefit of the doubt here and say that I'll probably end up liking the whole track.
Primal Rave sounds like it has a lot of potential. Reminds me of a more fleshed-out version of Dry Lagoon from Sonic Adventure
Overall, some standout tracks and a handful of meh ones, but nothing bad in my opinion. I'm hoping to hear a bit more diversity in the final project; there seemed to be a LOT of rock songs in the preview and, while they were pretty good, I hope the final album isn't flooded with them since a lot of the source tunes just don't seem like they'd lend themselves to that genre :\
I don't really know why I put so much time into "reviewing" a short preview, but naturally I have high hopes for the remix of my favorite videogame soundtrack of all time, and I guess I'm just really excited for this Thanks for putting this together!!
