mostly genres of rock. i used to be basically exclusively into J-rock/J-pop, but I've recently become a lot more interested in American/English bands as well. Green Day was the first band I focused on when I started collecting CDs; I have all of their albums from Kerplunk (1991) to 21st Century Breakdown (2009). Also been getting into Nirvana because of my sister.
when it comes to bands I'm super passionate about, it's mostly J-rock because of how extensively I listened to it as a young teenager. Polkadot Stingray is like, my #1, but SHISHAMO and MOSHISMO also have a pretty firm place in my heart.
