I think Punk (and Punk related genres) is what I listen to the most. Some of my favorites are
Infest
Lack of Interest
Negative Approach
The Fall
Discharge
No Comment
Ramones
Bad Religion
Minor Threat
2 Minutos
Pig Destroyer
Excruciating Terror
Crossed Out
and Hüsker Dü, but I prefer their Pop-ish alt rock era over the Hardcore one.
