What are BAMs? If you need track listings for C418's albums, you could check his Bandcamp or even his Musicbrainz entry (which should be the most complete set of metadata for his music)
For the equalizer I used VLC. (you can access the equelizer in the tools section.)
I recommend using the following settings:
Put everything except 600Hz at -20dB
Put preamp to 20dB
Enable 2 Pass
