The really crap posthumous Hendrix releases - I'm thinking of Dagger Records stuff but also (and especially) some of the earliest posthumous vinyl releases. I loved Axis when I was a kid and so when I saw Crash Landing in the record store, I bought it. Just about put me off Hendrix for awhile.
Everything by Sun Kil Moon after Benji. Captain Beefheart's Unconditionally Guaranteed and Bluejeans and Moonbeams.
There's about 15 live albums I'd like to erase from the Fall's discography, maybe more. All released posthumously, mind you. There's several unnecessary compilations and repackagings too. One could slim the group's discography down by a good 30 albums and still have every studio recording.
This album's been mentioned, but since I'd handle it differently I'll bring it up too, with same suggestion I recently made in another thread… —-— The Beatles | Yellow Submarine —-— When the remasters happened, I'd say the four exclusive/"new" Beatles tracks (which I love, and always just listened to as if an EP) shoulda been added to Past Masters as they were to Mono Masters— but placed between Rain and Lady Madonna. And the Martin side (which is pretty excellent) shoulda landed on a CD placed after his A Hard Day's Night soundtrack contributions — with maybe some highlights from his mid-'60s instrumental recordings of Beatles numbers in between — which coulda been included in the stereo box set, on the USB, and now up on the streaming sites.
It's got some poor moments, but Stand By Me is a loser? Slippin' and Sliden'? Peggy Sue? Do You Want To Dance? The Wedding Album, or Two Virgins would be prime picks long before Rock and Roll, no? My personal peeve of compilations is Gimme Some Truth. Listened once, put it away. All the previous comps sounded better.
