I'm a mix. I really enjoy finding new bands, even if they're not new bands. Recently I've gotten EXTREMELY into Lorna Shore (Deathcore/extreme metal band). I'd never heard them, they've been around about a decade, but they're new to me! Last year was the year of Bad Omens (Heavy Rock with some metal core tendencies). I've also been liking this synthy band The Midnight lately (like 80s electro pop complete with saxophone solos).
The way I find most of new bands is usually by either listening to bands I already like or have been into forever and using like "radio" feature on Spotify (Lorna) OR by searching out the openers for bands I like and checking out their music Bad Omens/The Midnight). It's so fun to come across an artist you've never heard and dog into their catalogue and realize they've got multiple albums filled with bangers.
