"It's now official that every Eurythmics album will be realeased in splendid remastered glory. Remastering means using digital technology to make the most of the sound of the original recordings. According to a press release Dave Stewart has supervised the whole process and each disc will contain rare tracks and remixes (some of them previously unreleased) as well as single sleeves, alternative, never-before-seen alternative artwork concepts and previously unseen photography covering the band's entire career. No track listings are available yet."

The link above contains some lists of possible tracks to be added.

The site you listed mentions the tracks which will appear on the remastered albums. Looks like it's mostly b-sides and 12"s and some unreleased songs. I was hoping they'd pu tin that unreleased album I heard about.

Back in, I think 1985, they recorded an album which wasn't released. It was all synth and according to some fans who Dave Stewart let hear, the songs were really, relaly good. Maybe they'll show up on a box set someday.
