I'm going to go ahead and throw the entire calendar year 1997 into my Hate Pit. From my research, no other year has provided as full a list of utterly unlistenable hits. Take a look:
Aqua, Barbie Girl
Chumbawumba, Tubthumping
Sugar Ray, Fly
Jimmy Ray, Are You Jimmy Ray?
Los Del Rio, Macarena
Elton John, Candle in the Wind '97
Toni Braxton, Unbreak My Heart
Spice Girls, Wannabe
LeAnn Rimes, How Do I Live
Hanson, MMMBop
Third Eye Blind, Semi-Charmed Life
Meredith Brooks, Bitch
The Verve Pipe, The Freshman
Savage Garden, I Want You
Sister Hazel, All For You
Paula Cole, Where Have All The Cowboys Gone?
Shawn Colvin, Sunny Came Home
Celine Dion, It's All Coming Back To Me Now
Sheryl Crow, If It Makes You Happy
Sheryl Crow, Every Day Is A Winding Road
Sarah McLaughlin, Building A Mystery
Donna Lewis, I Love You Always Forever
Eric Clapton & Babyface, Change The World
You can't name me a year that can fuck with '97's awfulness.
