Changes

'''''Sin''''' (also known as '''''[[Halo numbers|Halo 4]]''''') is [[Nine Inch Nails]]' third and final single from their debut album ''[[Pretty Hate Machine]]''. It was released on October 10, 1990 , by [[TVT Records]] in the US, and on November 4, 1991, in the UK. It contains three [[Remixes|remixes]] of the title track as well as a Queen cover.

In addition to the two CD configurations shown below, it was also released on various vinyl configurations and sizes: the US release is a 12" vinyl with red/purple artwork, while the UK had a release on 9" and 7" vinyl, both with black artwork. The cassette release in the UK was in exclusive "cigarette box" packaging, as opposed to the typical oO-card sleeve. The graphic and lettering on the US versions of the single is metallic gold, which sometimes appears black in photos and scans.

''Halo I-IV'' is a limited edition vinyl box set released by Concord/Bicycle Music for Record Store Day in November 2015. It contains the domestic versions of the 12" singles for ''Sin'', ''[[Head Like A Hole (halo)|Head Like A Hole]]'' , and ''[[Down In It (halo)|Down In It]]'' on 120 gram vinyl, as well as the original version of ''Pretty Hate Machine'' on 180 gram vinyl. None of the music in this set is remastered.
