80’s pop is usually a safe bet. I did a very intimate NYE party with an adult crowd accustomed to top 40 rubbish and what I call “Radio 1 indie” music. I played mostly 80’s pop, mixed/transitioned quite neatly considering, before moving onto some more mainroom piano housey kinda tracks and seeing it out with the music I actually love to DJ. Worked well in the end as most people (including me) were too pissed to realise they were raving away to Tale Of Us. I couldn’t bring myself to play any top 40 crap as the sheer dislike of it on my part would kill my vibe and probably translate to the floor.
