I'm just scrolling through some categories and trying to think of some picks... and some wishful thinking.
Best Metal Performance - It would be cool if it was KGATLW - Planet B (Or anything off Infest the Rats Nest)
I have a feeling it will be Tool - Fear Inoculum Unless it wins Best Rock Song.
Best Rock Album - I'd be shocked if Tool isn't nominated. I can't think of any that would beat them out.
Raconteurs will probably get at least one nom in either rock or alternative. Not sure who else would fall in here, but I really think King Gizzard deserves at least one nom in the Rock/Metal categories. I don't expect them to win, but Infest the Rats Nest was one of the best thrash albums in decades, and I think the fact that they are not a pure thrash band makes it even more interesting. Add it to the semi-tied themes/story from Fishing for Fishies - it has deeper insights in the writing than a lot of albums in these categories.
R&B - this is where I think Lizzo takes one home
Country - It will be interesting to see if Sturgil's new album is counted as country or rock. It will be AMAZING/Hilarious if Old Town Road gets a nom under country. Or would that have been last year?
Best Comedy album - I think Chappelle takes this one, but I hope Gaffigan gets another nom. I think he got robbed last year with Nobel Ape. He went into some heavy dark stuff and came out laughing on that one. This year though, Cheppelle by far has the most intelligent and challenging special in my opinion.
Packaging - I think Tool was obviously going for this award with their latest release. It would be cool if they announced a vinyl box in time to be considered for recording and box set, and won both.
Engineering: Non-classical - I think Billie wins here too. Her album has surprisingly connected well with the audiophile community, which is usually a good indicator for this category.
Remixed Recording - Old Town Road has to win this one based on the sheer number of entries. I mean come on, they did like 20 versions of it! lol
I actually have no idea who will win that.
Surround Sound - Did they do a surround mix of the Beatles - Abby Road? If not I feel like Pink Floyd/Roger Waters wins this any year they put out a surround mix.
Music Video - TSwift will be nominated, even though her video is trash. I think Billie - Bad Guy will win. I wouldn't be mad if Lizzo won. I'm not sure who else would be a major contender here.
Lastly, BOLD PREDICTION/HOT TAKE - TSwift wins zero awards this year.
