there is a mistake on D#7: Open the Door, Homer T2 is missing. 
(T2 is the one with the laughing on the first chorus). The ones labeled T2 & T3 are both versions of T3, so I've recompiled the disk and amended the artwork. 
The mistake occurred because the one on the original 14 song acetate is T3, and I had labeled it as T2, so when I added T3 from the 20 song acetate there were two versions of T3 (and T2 was missing!) 
(there is an incomplete T2 on one of the other Disks, but this is the full one).
