I do think that, from a "levels" standpoint, having 4 separate songs would make the most sense, and the second-most-logical thing to do would be one long song, so breaking it into 2 parts kind of makes the least sense. But I do agree that from a song-lenth standpoint, and a price standpoint, two parts would be the best solution, and I think when all the factors are looked at together, the two parts idea still comes out on top. So I say stick with it.
Might I also suggest just naming the separated songs "Levels 1 and 2" and "Levels 3 and 4"? Seems like that'd make the most sense, since there's no real reason to be less straightforward about it. Especially since, as far as I can tell, there'll be no other way within the game itself to see what "levels" each song is comprised of unless they are explicit in the title.
