I am blessed with the ability to listen to music ironically, so bad songs don't anger me I usually thumbs down songs on Pandora just because I'm sick of them.
That being said a few pet peeves:
I had a couple groups of friends growing up. My metal head friends and I had a saying: "A little Bob Segar is too much Bob Segar"
I have the same feelings regarding JourneyStyxForeigneretc.
A really bad song: "Dust in the Wind". I think that maudlin sentimentality is what sums up all that is wrong about the era and those bands.I give Boston a pass, they had their own thing going on.
Drunk, drugged Aerosmith writing their own songs: good
Sober Aerosmith with a commercial songwriter: bad
Always hated hairbands from day one. I was a teen in the eighties and hated what was available for contemporary music except a few like SRV and Metallica. GnR's Appetite for Destruction was a nice break in the late eighties but mostly I listened to classic rock and went to see those bands who were still around.
I remember switching between station when hairbands were big and all of a sudden I heard Smells Like Teen Spirit" and said WTF is this. Thanks to grunge and other hard rock like AIC, Soundgarden, STP, etc I could listen to current bands again although no time for concerts with a baby and Law School.
Some worst offenders: "Living on a Prayer", "Every Rose has a Thorn" and whatever it was Cinderella did. It's fun to watch the videos ironically though.
I don't hate the Eagles but given that they are the best selling American "rock" band ever they are vastly overrated.
Lastly, I love Led Zeppelin. They may be my favorite band. But I wish "Thank You" never saw the light of day.
To sum it up, I hate maudlin BS in all its forms.
