Oi. You're talking about my ska band's core audience there
Admittedly it's not my favourite from the set, but it is surrounded by absolute bangers so I'll let it off.
The one song we all loathe and will never play is My Boy Lollipop, which seems to be getting a right kicking in this thread
There are many songs I dislike but few that I actually hate. Freebird is one, Layla, Cher's 'Believe', but for me the #1 unflushable turd is The Mavericks' 'Dance The Night Away'. Fingernails down a blackboard.
