The Replacements - Tim (Ed Stasium Mix)
 

The Ed Stasium mix of ‘Tim’ is absolutely amazing! One of the best re-mixes in the history of rock & roll. Seriously great.

Reissue of the year, bar nothing.

A close second, though, is The Complete Obscure Records Collection 1975-1978. Given that it was released in late November, however, you won't see it on many year-end lists, because apparently the musical year ends in October or something. Idiots.
