Jokes aside, the new remasters sound really nice, especially Can't Buy a Thrill, which is almost like a new album. I don't know though what else you could do to the later albums, because their original masters sound great already.
Lately, I've been on a metal kick, what with the new Metallica album stirring that urge. Before that it was mostly Americana, with an emphasis on bluegrass. It goes in waves like that for me, where most of what I play is within a general "vibe", though not necessarily the same genre exactly.
This is such a hard question to answer, but recently last dinosaurs, I really like their sound.
Also betcha, an underrated band with amazing talent and sound, my favorite song from them is July.
Mostly hard rock and metal. Band-Maid, Electric Callboy, Blackbriar, The Warning, The Pretty Reckless, Liliac, Sabaton, Battle Beast, The Hu, Bloodywood, Polyphia, and Visions of Atlantis.
Basically heavy metal revival:
