English needs a better term for "least favorite"

I've worked in supermarkets and coffeeshops, and have thus listened to a lot of terrible, repetitive music, but nothing beats the music I listened to on the job I just quit.

It was an office, and most of the day it was just my boss and I in there.  He had a CD player with a single album in it.  The album was a bunch of famous songs covered by Korean women, with synthetic backing sounds.  The songs included: "Memories," "Dust in the Wind," that opera tune by the blind Italian guy, and "Have I Told You Lately How Much I Love You."  They were all sung in the same high, lilting voice, and I could just barely make them out, being a good 20 feet away.  But that first note of "Memories" always brought me back.  And this CD was on repeat FOR 18 MONTHS.

Yes.  Through interviews, inspections, tense talks about going out of business, that album was playing throughout, no breaks.  I think it was on all night, so the cleaning staff could enjoy it as well.

But I am thankful.  I will never find an album I hate more than that one.  There's something reassuring about this.
