Other than UU and fragaria I also love tsukipro/tsukiuta, ainana, paradox live… I also really like aaside, technoroid, and a3 but I’m less familiar with the songs outside of the anime for those (I do wanna explore more though)

I really love a3! They have a lot of good songs ainana really one of my favourite...i just finished to rewatch tsukipro!!!
