scumbag music
a term coined by Youtuber Pat Finnerty which describes heavy rock music from the late 90s and early 2000s. think Creed, Staind, Puddle of Mudd, Dope, 3 Doors Down... you'd probably hear it on a playlist at a college gym. often they use a "yarl" style of singing and employ "scumbag tone", which is a heavily distorted and muddy guitar sound, often provided by a Mesa Rectifier. the lyrics mostly focus on problems and pain, and occasionally drinking and fighting.
Nickelback is one of the ultimate "scumbag music" bands
