Favourite Singer - ABSOLUTE Worst Song

Ok if someone asks your favourite singer you say… I like XXXX

Now almost no one, likes every song that person’s recorded

So let me ask you to name your favourite singer (or at least one of your favourites) but their absolute, and I mean absolute worst song. Obviously this is just your opinion but what song by your favourite singer made you think “Just what the #$@!! were you thinking”
Mine:

One of my favourite singers: Olivia Newton-John
Worst song: Heart Attack. This is GARBAGE… LOL It went to #2 on Cashbox and #3 n Billboard but it was horrible.

Not exactly what the OP is looking for, but here’s the most hilariously bad song ever, so bad that it is in some ways great! The most unwanted Song
