Megadeth - Been a big Megadeth fan for about 15 years now. They have their ups and downs in a few areas, but I generally love nearly all of their albums and Dystopia that just came out is one of their better ones in years.
Ghost - I use to not really like this band, but they were getting rather popular in the metal community, so I tried again after Opus Eponymous with Infestissumam and got hooked and I've been listening to Meliora regularly since it released last year. I even got to see them live and holy crap do I recommend them. Genuinely good.
Devin Townsend - Basically anything Devin has done. Some of his ambient stuff I'm not super into, but his career spans across so many different moods and genres and he's just an incredible talent. My favorite album might be Ziltoid, which I've listened to a ton. Ziltoid 2 wasn't quite as good, but still has some solid music and he's rarely, if ever, bad. I can go all the way back to his insane Strapping Young Lad days if I want some truly chaotic music.
Babymetal - Weird one to add, I know, but while I generally enjoy a mixture of Japanese Pop, Rock, and Metal, this band just really came about to deliver something fun. It's very happy and and fun and I think that's something you really don't see much of in metal. So much of metal is about death, violence, alcohol, satan, etc, and that's fine, but it's not often to find like upbeat metal and I don't even really know what they are saying lol It's "pick-me-up" music and I've listened to them so much since they released their first album. Even with the second album being more "mature" and less silly compared to the first one, it's still so enjoyable.
Might be a few others I can think of that I feel really fit into something I listen to a ton and very consistently, but drawing a blank at the moment.
