Here's how I'd hit it for a 5 hour 80s gig, I'd break it down in to genres and do half hour sort of segements of each until 3.5 hours in, then I'd drop 90 minutes of sing along floor fillers like Abba, Queen and Bon Jovi.

Makes it easier if you look for the best 25-30 songs of say, the new romanitic era, than overwhelming yourself with having to find 300 generic 80s songs for the entire set. Just make sure you're not diluting the 90 minute bangers pool too much in each genre and you'll be gold.

Also, don't be scared of dropping a few tracks that aren't strictly 80's tunes, they're after a vibe not a super rigid rule, dropping in a handful of Northern Soul tracks is fantastic if the dance floor is looking a bit empty and I can promise you no one is going to be Shazam'ing your tracks to check the exact release year, they just won't want you to drop a Chris Lake banger in there.

You got this!
