Great. Most of these songs can be found on albums available from each artist. Some of the vocals sung in-film are disregarded for the professional versions that do a good job of white-washing credits with tinny soundtrack. But what I find to be greatly disappointing is the sore lack of Danny Elfman's contribution to the film in this 'original soundtrack.'
Try again, studio.
Look for 'Music for a Darkened Theatre, Vol. 1' if you want to hear Elfman's number and don't mind receiving a whole package of his other work.
