I either watch an episode of Trash Taste or just listen to some music
I like a wide array of music so it just depends. Though it is fun to listen to bgm from gundam.
When I did use to build, I never listened to anything.
some podcast (mostly TrashTaste) or someone's Livestream (i'm usually watch : Lululuvely,CourageJD and OperatorDrewski)
Slasher movies
Gundam
What do you think?
