Music Preferences
Mainly on a song-by-song basis, but in general; techno, electronic, VOCALOID, some soft rock

Warm and bright audio, with a low-bass boost (30/60Hz) and accentuated treble (16k boost). Strong preference for treble.
Otherwise prefer a flat and neutral device with malleable output that responds well to equalization.
