It depends what your definition of B-side is. If it's only tracks released on CD or vinyl singles from a studio album (which is what I guess your definition is) then your list is correct. However, I consider it any track that wasn't released on a studio album, meaning all the EBW's that weren't released on album and all the tracks on the bonus disc.
Anyways, I'm not sure why you've included Delik and not EBW6. Delik is just a "remix" of Life is Sweet. But really, they are both like completely new songs that uses the same samples as their A-sides. Seeing as EBW6 was released on AmericanEP along with HIA, either it should be included or Delik should not.
Anyways, anType should probably be the one to decide, since he seems to know everything about the Chems and their releases.
