I don't call myself a fan of many things, because most of the time I like only some musics, some things that they're doing, etc.
The exception would be Asian Kung Fu Generation, which for me works fantastically.
So I'd say
Fanclub
and
World World World
-indie j-rock
The licks, I could put them on loop all day long...
And also
Kaggra -
Core
An 'neo-japanesque'/kei thigie.(this album is less 'weird', they use less make-up... And has a bit of electronic.) (And hipster-fanboys would hate me for saying this(if they still exist :D))
[size=10]They are the first two bands I started paying attention, makes sense[/h]
