There are multiple artists with the name Bad Habit.

1) Bad Habit is a Swedish hard rock band founded in 1986.

2) Like many great punk records, this one’s almost over before it starts. While this isn’t quite great, it does cover all the hardcore bases: fast, loud, aggressive. The four song demo clocks in at just 5:39, but it lets up very little over that time. Bad Habit draws a lot from Minor Threat with just a slightly looser approach a la early Black Flag. They throw in a bit more melody on "Cancer" and it sows the seeds of being more than just another young punk band playing fast and angry. Remembering that this is a demo, a preview of the future so to speak, and that they’ve only been together about six months, it’s an exciting listen. The production is acceptable, but not exceptional and the performance is passionate and honest. Lyrically, they cover the typical topics of frustration, alienation and family breakdown and while the lyrics aren’t poetry (c’mon, it’s hardcore not folk music), they’re heartfelt. To keep things from getting too serious (something so many hardcore bands forget to do), they also throw in "Israeli Girl," an ode to the girl of their dreams, Natalie Portman. I wonder if she’s heard it..." just to make things clear though...natalie portman is all me (joe)

3) band starting out in adelaide, australia consisting of 'callan xixi paul ryan'

4) Shortly lived bulgarian alternative metal band

5) An Irish folk band, based in Leeds, UK and formed in the early 1990s.
