Before reading, please consider this:
I would wholeheartedly recommend this soundtrack if they fixed the misleading discription. This soundtrack was one of the main reasons I decided to purchase the game in the first place and I think they did an excellent job on it.
If you don't understand what I mean by "audio quality" and "kbps" then you should look it up and enlighten yourself, don't down-vote this review for helpfulness because this isn't about opinion.
Now here is the problem:
The description says that the soundtrack includes "every song in the game at 320kbps CD quality."
These are all the songs that do not meet the advertised quality of "320kbps"
Target World (Shang Mu Academy) -----128kbps
Up the Creek (Jade Creek 1) -----256kbps
Up the Sub (Jade Creek 2) -----256kbps
Pangu Lagoon 1 (English) -----128kbps
Pangu Lagoon 1 (Japanese) -----128kbps
Time Attack -----128kbps
Relic Maze (Extended Mix) -----256kbps
Freedom Planet Theme (Orchestral Remix) -----128kbps
Beta Dragon Valley 1 -----128kbps
Beta Minor Boss Battle -----128kbps
Beta Speed Powerup -----128kbps
Beta Title -----128kbps
The information I am presenting you is FACT. These values were obtained from opening the sound files and reading the detected audio quality. The reason I have zero hours of playtime is simply because I use a different music player than the one on Steam.
If they say this album is 320kbps, then ALL of the songs in it must be at least 320kbps. I will change my review to "recommended" as soon as either the sound quality or discription is fixed.
P.S. If you want a better quality version, you can get it on Bandcamp for a few dollars more.
