Same with me! =)!! I ussualy listen to music while doing unwraping model or drawing.
The music I listen too ussually depend on what I'm doing.
I love metal music and ussually listen to it while making model or unwrapping, when I'm drawing
I ussualy listen to soft music or techno depend on what I'm drawing too.
The music below and the download link are legit as the artist release them for free so feel free to download it. (expect for I don't list below
