About
All songs copyright 2010-2011 Deceased Superior Technician.
Songs were made using FLStudio version 9 and encoded using LAME mp3 encoder.
Songs contain no unlicensed samples. All songs are free to use in videos and video games, both free and commercial. Songs may not be redistributed or sold.
This collection is comprised of songs that I feel might be good for your game. If you have no music, 'borrowed' music that you don't own copyright to, or bad music, you can use these to upgrade the music in your game. You do not have to put a link in your credits; though i would appreciate it if you did. Thanks, and Enjoy! -DST
