if you can put REG EXP functionality into mp3tofid, it would be a great help. symlinking all the files that match a criteria manually would be too tedious. i was thinking that if mp3tofid comes across a directory with just a specially named text file containing a regexpression, then it would add everything that matches to a playlist which is named the same thing as the dir. (look at emptool source for regexp code, i would imagine).
btw, have you been able to implement the crc check that would be compatible w/ jemplode?
