Needs some OpenGL or DirectX coding so I can record with Fraps. D:
As you get the ID tags of every song, they're still listed in filename-order, so you get what appears to be a random list, it's be nice if it was sorted by song name.
Also, on the score at the end of the song, can you include what difficulty it was, so I can prove I was playing on fast.
Also, to Fluffey, see the screenshot, I've almost done it.

2 Little bits got through at the one section near the end where you get loads of lines that split up.
