I either find them hugely irritating, mindlessly positive and over enthusiastic and insincere like Zoe Ball ( have to turn her off in the morning,she's too much and I fear she's going to spontaneously combust with over excitement ) Elaine Paige ( with her incredibly annoying gurgling laugh), Sara Cox and Lisa Tarbuck ( with her stupid zany voices, cringe ) or insufferably earnest and pretentious like Jo Wiley or Mary Anne Hobbs on 6 Music.
Tbf I did like Annie Mac, Annie Nightingale and Janice Long but that's probably because they seemed genuinely into the music they played and weren't twats.
I'm probably being unreasonable but I honestly can't bear to listen to them!
