You know. The one that is awful, but still creates that earworm and makes you turn up the volume when you're by yourself. I'm sure I have several, but this is definitely one of them.
I have a secret place in my heart for Fernando by Abba: Doesn't get much cheesier than that. If you ever bring this up again I'll totally deny it. At the moment I'm really enjoying this by the Zombies: Not sure it totally qualifies, but it seems like it might.
Most of the ones listed simply aren't cheesy enough (which is a requirement per the OP) These are more like it, with extra cheese:
I used to have a compilation of like 25 CD's from Rhino called, "Have A Nice Day" full of one hit wonders of the 70's that was loaded with top shelf vintage cheese. Here's a couple:
Cheesy as bell, but I turned up the volume every time I heard this song on the radio in the late 70's!! Spoiler: Mandatory "Born to be Alive" ... ....... ....... .......
The "other" Chumbawumba song. I liked it because Fox used to play this years ago in Baseball commercials.
Pretty much any Weird Al works here, but I'll post my two favorites (though I can easily post 20 more) First is a classic. 2nd I like because it is all done in one shot-take, which is rarely ever done. IMO, both are fun & worth the watch.
