If you go back you can see that I said I thought REM & Fleetwood Mac albums covers are bad, as I did in the Genesis solo albums thread. I have never liked the covers of Fleetwood Mac & Rumours - I find them pretentiouus & off-putting, and yet they are better than Tusk, which is awful. As for REM, the cover of Automatic For The People is dreadful, but so is Out Of Time (which I will always consider a better album).
Most of Paul McCartney's & Elton John's covers are good. The cover of Band On The Run & Goodbye Yellow Brick Road are etched in my brain.
Pet Sounds by the Beach Boys - overrated album & horrible cover.
Bob Dylan - most of them are dreadful, except for Highway 61 Revisited & Desire.
I would imagine that if I mention Love Beach by ELP you will all know what I am talking about. Apparently it's also a bad album.
Frank Zappa did some good covers - Broadway The Hard Way where he's just smiling, unexpected.
Those are just a few examples of both good & bad.
