Virtually all country pop music (exceptions made from the classics like Patsy Cline)
Anyone from American Idol or other TV show
A large swath of pop music
Hinder (the records execs must be smoking crack)
Akon (a no talent A-List moron)
Nickelback (Oh Canada! You're killing me!)
a large swath of rap and hip hop (I prefer old school--Sugar Hill Gang, Beasties, etc)
Like Shelley, I am a music snobbola. At age 10 I discovered Led Zeppelin and the Yardbirds and soon devoured a huge 60s and 70s music catalog as a mere child. I had probably about a thousand cassettes before hitting my teenage years. I've listened to punk, metal, and their related sub genres. I also like good dance music (which could include any number of genres) and love jazz (right now addicted to Coltrane, Brubeck, John Scofield, Shamika Copeland) and classical (love Shostkovich and Liszt), as well as blues. You'll likely find me at jam band festival such as Bonnaroo, Gathering of the Vibes, or the Newport Jazz Fest as well as the occasional classical performance.
Basically, if you hearing it on the radio, seeing it on tv, or hearing people talk about it at the water cooler it probably stanks....in my opinion of course.
