This Creep CD single is essential for two reasons: the Blow Out remix, which is a great alternate take of the album version, and Yes I Am, which is probably the best of the PH b-sides.
Blow Out, on album, is a very good mix, but there's not the sense of buildup that's highlighted in this version. Note that it's not a remix as the term is used now; it's an honest-to-goodness different version, remixed from the original recording tapes.
Yes I Am isn't mindblowing, as some of the Bends-era b-sides were. It's a competent song, with decent development, and some interesting lyrics, but it's about as good as they left off the album. I prefer Million $ Question, but Yes I Am is good.
The live version of Inside My Head improves on the original, with the vocals delivered far more passionately. It's a catchy little song, and fun to sing along with, but it just feels lacking in some way.
The ostensible lead track of the single can be safely disregarded. It's not a radio edit, for what it's worth, but I hope nobody would buy this single for Creep.
