Applying promotional song credits to iTunes Music Store album purchases

Q: If you have song credits at the iTunes Music Store that were acquired through a promotional offer, can they be applied towards the purchase of an album? If so, at what rate? The reason I ask is that several albums have digital booklets, videos, and/or “Album Only” songs. If I have 10 single-song credits (retail value $9.99), why can’t I seem to be able to pool them and purchase an album worth the same value?

A: Unfortunately, the iTunes Music Store simply doesn’t have this capability.

Why? We’re not entirely sure. It could be a licensing issue, or it could just be that Apple doesn’t want to lose more potential revenue beyond that lost from the free credit that has been provided.
