Some really cool songs don't have music player blocks, and I think it's a massive massive waste, since they're really cool! Especially theme4, "Players could hear this music while they are at the world selection menu when the Firefighter Pack was released." The suspended (the one that plays right before a server restart) song is really nice, too, but was never added to a music block, and I think it's a waste (could be a hard-to-get, considering it's such an important song).
