I will be very interested in an Immortal soundtrack of Michael's music. But for me it will be nothing more than a novelty album, as I heard The Beatles, Immortal album (and The Beatles are my favorite group) and even though it's very well produced it's not something I'd go out of my way to listen to. I'm not really a fan of remixes any way which is what Immortal soundtrack albums are.
I used to love listening to the remixes of Jam, In The Closet, Remember The Time when they were released in 1992. But after a few years they just sounded like gimmicks, which in my opinion are what most remixes are and I rarely listen to them now.
I very excited about a Bad 25th Anniversary album being released. But I don't want it to contain fresh remixes of songs, like Thriller 25. I thought the the content of Thriller 25 musically was very underwhelming, with those gimmicky remixes by will-i-am, Kanya West, and Fergie singing Beat It and Akon singing 95% of Wanna Be Startin' Somethin' 2008. Just a total waste of space that I think was a bad move by Michael. Thriller 25 was nicely presented with a new album cover, booklet with few unreleased photos and a brilliant DVD page of Michael's Thriller era music videos and his Billie Jean performance on Motown 25. But I'm pretty sure most fans like myself re-bought the Thriller album for more than the 2nd or 3rd (I think I've bought over 10 copies of the Thriller album since 1983 in different formats and versions), for those things and for an official version of the bootleg (previously unreleased) For All Time, and not for the remixes with current artists.
I would like a Bad 25 to be more like the Thriller Special Edition from 2001, which had brilliant content of one unreleased song Carousel (but it was a bootleg like For All Time that had been heard by fans for quite a while since the around 1995, and known as Circus Girl), and a rare song Some One In The Dark, a great truly unreleased demo of Billie Jean (Home Demo From 1981), and another truly unreleased demo of Michael and Vincent Price doing the voice over for Thriller. It may have been thin on Bonus Material in my view but I really liked what I heard and it put what made the Thriller album so amazing, and Michael's genius more clear because the music wasn't tampered with by other current producers who had nothing to do with the Thriller album. Who's remixes dated quickly, against the original versions of songs on Thriller both released and unreleased that always sound current and fresh. I don't want to hear any current artists and producers remixing Bad, Man In The Mirror, Dirty Diana or Smooth Criminal. I don't want to hear covers by current artists singing Michael's songs, because I don't like hearing other people sing Michael's songs, because even great vocalists sound flat when they sing a Michael Jackson song. I hated Alien Ant Farms cover of Smooth Criminal, it very childish and gimmicky, and not refined and cinematic like Michael's original version.
I would like to hear unreleased songs from Bad, like Apocalypse Now, Crack Kills and other songs. And demos for Bad and Smooth Criminal etc. Maybe one or two live versions of songs from the Bad Tour like Another Part Of Me, Bad and Man In The Mirror. It would be nice for Bad 25 to come with a Blu-ray or DVD, with a full Bad Tour concert from 1988-89, or full performances of one or two songs from the Bad album. Or even behind the scenes Making of documentary's from some of the videos from the Bad album.
