Here's an idea. Basically, you can trim a section of a song out, either by physically modifying the file, or by making the program skip over that part of the song (preferable, as I would like to keep the complete songs if possible).
Would make things a million times easier since the timing is already set in the beat file, so you don't have to re-time it using another program you probably don't use for anything but for trimming.
