I'm not ashamed of my music tastes, it's weird and eclectic, but I listen to what I love. I've noticed that I go through phases with music, I'm in my Happy-Go-Lucky music phase now, with heavy Irish seasonings.
I have two friends who are metal heads and once owned a CD shop. They give me HELL over my music tastes. I took 3 weeks of shit over going to the No Doubt concert a month ago. Here are some of the bands I listen to that they give me crap about.
Jimmy Buffett
No Doubt (Pretty much all 3rd wave Ska bands I listen too)
Beach Boys
Blink 182
Flogging Molly
Garth Brooks
Presidents of the United States of America
Daft Punk
Loreena McKennitt
Eve 6
Soul Coughing
Gaelic Storm
