this code needs some serious testing:

Note:
The song name optimization i think is worth it, saves about 200k of ram on my syste, however, having to create directory names iteratively each time we print probably isn't worth the cpu.  We only save about 10k of ram for the computer todo alot more work, and the code maybe a little messier
