EAR WORMS: Discuss - John Paul Young 'Love Is In The Air' Disco Classic ear worm but what does that mean?

 Speaking of ear worms ( I Feel Love, loads of Bee Gees of course who went on to Saturday Night Fever and the John Travolta schtick which frankly left me cold cold COLD but what is it?!) what is it about disco? Now this should start a row! . . . . . . . 

This is something I never cared for at the time but listen . . . . . . . . has this song always existed?

It seems like it to me. It is near perfect as music goes, disco I grant you but the phrasing the instrumentaion and the song and John Paul’s singing, the melody has always existed somehow which makes it an ear worm and then some?! NO?

As its Friday and people head off to the clubs and night spots loads of MY generation went out to dance to this

Ear worm or disco monstrosity? Both?!
