Hmm, I noticed these songs are ripped as 256kbps MP3. However, I'm rather certain the original game's files were encoded as either .OGG or .MIDI, and varied in bitrate. If you put the .mp3 files into a spectrogram, such as Spek, you can see the extra data generated by a forced conversion to a higher bitrate. I would appreciate an upload of the raw files, for audio fidelity's sake! No hard feelings, though.
