Your vote for greatest (covers) album

Mine is Annie Lennox "Nostalgia". Not only is she one of the greatest female voices ever, she knows how to make a song her own. 

+1 mammothguy54! Bowie's Pinups is great! I forgot about it! Thanks for the reminder!
Once a week I listen to the version from Nina Hagen and Apocalyptica of Rammsteins "Seemann" - it is amazing.
1-Jethro Tull “Thick as a brick” not just for the music talents but also one of the best produced albums ever.
2- Doors “ LA Women”
3- Pink Floyd. “The Wall”
4- AC/DC “Power Age”
Zappa's "Overnight Sensation" is a fascinating cover... Oh, you meant cover SONGS.
