A beat-driven, whiney techno-punk band from NYC who gets in your head and doesn't get out. Their live shows are great.
Yo, I got that Mindless Self Indulgence CD! It's got 30 tracks yet manages to still be under an hour!

1.) To masturbate
2.)Forget Blink 182-3- and 4, Mindless Self Indulgence (MSI as they are known to their loyal fans) is a punk band in its truest form whose name manifests itself during their incendiary live shows. Their music is a hybrid of Atari driven electronics with a venomous splash of A.D.D Punk Rock. MSI is the breath of fresh air that is sure to offend your p.c. restrained, category demanding, humorless peers.
I totally msi'd last night. it was great
ORRR That msi show last night was better then masturbating, or even real sex. I kissed Jimmy Urine for only a dollar!

A band that is classified under their own name and that of which is evil yet delicious. the left rights are a part of the consits of Little Jimmy Urine, Kitty, Steve Righ? and Lyn-Z..very awesome.
I wish that the band Mindless Self Indulgence would come back to Norfolk so I can fuck Jimmy Urine
