In March of 2007, Sony decided to go through all of Elvis' masters. They retransferred everything and remastered all tracks including repairing as many clicks, pops, bad edits and dropouts as they could. They have used these newly mastered recordings on their new releases since 2007 including budget soundtracks, 'Legacy' releases, the 30 disc 'Complete Elvis Presley Masters' collection and the Franklin Mint package.
Notes from a review of 'Jailhouse Rock Volume
1 (FTD)' by Piers Beagley
Treat Me Nice
(CD1, Track 6) The Original - On the final session
Leiber & Stoller re-arranged the song with
a much slower tempo giving the lyrics a new understated
cool-swagger. With a lower key this also gave
the song a sexier feel and lines like, "You
know I'll be your slave" take on possible
alternative meanings. It is an all-time Elvis
classic song and very different to the versions
Elvis actually recorded for the film. As a bonus
here we also get the Elvis count-in.
