Stevie only produced 'Bad Weather' for the Supremes didn't he? That's probably my favourite Supremes song of the lot (including the Diana Ross era). Have to second the vitriol for 'I Gotta Feeling' - Will.i.am has been a blight on music for a good decade now, but this is perhaps his nadir. 'Come on Eileen' is also a song I refuse to interact with - it's just there (like 'YMCA') for people who can't dance to have something to do and nearly always ended up in everyone with their arms round each other forming a large circle towards the end, which would inevitably collapse as the participants were all hammered, then resulting in a quasi-fight. A couple of contenders from my experience of 80s nights/wedding discos: 1) 'Wake Me Up Before You Go Go' by Wham - I realise they weren't trying to be Leonard Cohen, but it's their most annoying and insubstantial song, plus it has an odd rhythm that makes it difficult to dance to, which makes its status as a wedding disco classic all the more baffling. 2) 'Like a Virgin' by Madonna - her whiniest song by a mile. I used to go to an 80s club night years ago and though the music was generally pretty good, the DJ was obsessed with this song, which would be played pretty much every week and would be the only Madonna song he'd ever play. Given that you have the superior 'Holiday', 'Lucky Star' and 'Into the Groove' among others to choose from, I never got why he was fixated with this one, her worst single from her imperial era. And ... 'Manic Monday' by the Bangles. I loved their Greatest Hits but would always skip this one. It's one of Prince's most irritating lyrics. The only way to lighten the tedium of hearing it was to come up with alternate lyrics for the chorus ('my "oh God I weigh a ton" day', 'my decapitate-a-nun day', etc).
