As for Hot Space, Roger and John disliked both that and Jazz. But as for specific songs: Fred & John didn't like Gimme the Prize, and apparently Brian didn't like Don't Stop Me, as well as Roger wasn't so thrilled about Another One Bites
Brian only didn't like Don't Stop Me Now cause it's got hardly any guitar on it and he was being a baby. And Thank God It's Xmas is good I think. And there a some very good Xmas songs I think.
Merry Xmas Every one/body - Slade
Xmas Time - Darkness
Do They Know It's Xmas - Band Aid
Fairytale Of New York - The Pouges/Kirsy McColl
I even like All I Want For Xmas by Mariah Carey
