Top 10 Fictional Collaboration Albums that Would Be a Masterpiece

The Top Ten
1 Nightwish & Within Temptation
2 My Chemical Romance & Tokio Hotel
3 Black Veil Brides & Tokio Hotel
4 Rammstein & Jackie Evancho

That would be kind of odd to be honest.

5 Evanescence & Linkin Park
6 Björk & Aphex Twin
7 PJ Harvey & Liz Phair
8 Madonna & Lady Gaga
9 The Birthday Massacre & Sharon den Adel
10 Lupe Fiasco & Kendrick Lamar
The Contenders
11 The Beatles 71-72

Could have been the greatest album of all time, just think about a single disc released with the best cuts off of each Fab4 member's first two solo albums, which of course was mostly all unreleased/unfinished Beatle material. Even Ringo had a #1 solo song at that time "It Don't Come Easy". Songs like "Imagine", "My Sweet Lord", "Maybe I'm Amazed" and many more would be awesome. There is an unfinished Beatle demo version of "Beware of Darkness" that is absolutely chilling, though the version later done by George Harrison and Leon Russell at the Concert for Bangladesh is the one that got all the attention.

12 ABBA & Boney M.
13 Shakira & Anastacia
14 Liz Phair, Avril Lavigne & Miranda Lambert
15 Rammstein & Tarja Turunen
16 Rammstein & Marilyn Manson

Manson was in a Rammstein music video so I guess that counts.

17 Black Veil Brides & Marilyn Manson
18 Linkin Park & Hollywood Undead
