I'm rather eclectic, and it sometimes shifts based on my mood. I really like being exposed to new music but if I had to nail down a few trends that I find myself often coming back to they would include:

Symphonic/Pop/other Metal, love Amaranthe/Nightwish/Rave the Reqviem/Dragonforce (I know, lol)
Classical, Two Steps from Hell
Punk/Rock, Paramore/Hey Monday/Similar
J Pop/Punk, AliA/*Luna/My First Story/Reol/Nanawo Akari
Lots of Vocaloid/Anime and EN covers of such, love Rachie, Jubyphonic, Lizz Robinett, and AmaLee

As well as many more one-offs that would take forever to mention, hehe. Honestly pulling up Spotify's discovery playlist is one of my favorite things to do each week. If anyone uses it and happens to want a 20 hour brick of my aimless fav searching here's a link to my current list~! https://open.spotify.com/playlist/3euGSDxLzO9mI1IjKZebf5?si=b0bb67f8128e4a26
