Not mad, making the point that he objectively wasted his time.
What purpose is there of playing a song at 200% speed? Then throw in hes not doing it on an actual instrument but rather a toy in a video game where hes not actually producing any sound but just pressing buttons meant to mimic actual music.
And he did this for 9 months, approximately 1% of an average human life.
You don’t have to pretend to appreciate people doing frivolous stupid shit - it’s ok to call bullshit you know?
