Only if you have Part 1

Only get this if you have part one and want to complete the set. The first track, "march of the pigs" is right off the album, so now you're down to only 2 tracks. "Underneath the skin" is an insturmental of reptile that's about seven minutes and thirty seconds long. At times you won't be able to tell what part of the song you're listening to but then you'll find yourself because the insturmental stays pretty much true to the song all the way out. The last track "reptilian" is a standard remix of the song for the Downward spiral/ Further downward spiral era, it's nothing extraordinary but it is highly enjoyable. If you're trying to decide between this and the 5 track version I recomend getting this because of the extra tracks, neat little c.d case and because of the sound quality.

A welcome, but not essential, addition to any NIN collection

If you are buying this import, chances are good that you already have the LP version of "March of the Pigs" and are more interested in the other two tracks, so I'll get right to it:

"reptilian" is a decent remix of "reptile"...not exactly earth shattering, but good as usual, with some cool delay and stereo effects at the end.

"underneath the skin" is another remix of "reptile", this time mostly instrumental. The quality is similar to "reptilian".. Good as usual, but not exceptional.

Overall, I would say that this single is more for hardcore NIN fans and collectors looking to find all of Trent's tracks. Most casual NIN fans wouldn't find this one worth the money.
