Replaces Bebop's A4 with sections from Picayune Dreams Boss Themes including aberrated and secret  (spoilers for Picayune Dreams) variations that I find pleasing. 
There is also many a file which is uncropped, taking unnecessary space. I will be cropping them properly when my mind finally enters a state free from the dopamine overdrive of Deadlock. If you wish to have a smaller file size for the sound mod, please either take the hard path and optimize it yourself, consult other people who are either unaffected by the dopamine that Deadlock provides, or ones who have broken free from the dopamine. You may ask me for permission to upload.

If milkypossum wishes to take down this mod, as it may break some of their rules regarding the usage of their music, they may contact me through the email I have emailed through their bandcamp.
