I decided to import this soundtrack since I'm a big fan of Fire Emblem. As I was listening to the music I noticed that it sounded off. I decided to use multiple software to test the music and found out that the problem wasn't my hearing, but the discs themselves. The music quality is pretty low (16 KHz).
If you are buying this to experience music in high quality then don't waste your money, because you will get probably the same quality the gamecube game has.
