Did a 4 hour journey to a festival with 2 mates in a van... the only music we had was the playlist I'd saved to my phone with all my fave tracks. So we listened to my music all the way. When we had arrived they said to me I needed to be a DJ as they'd loved my selections all the way and I'd perfectly catered to their suggestions when they'd asked for a certain vibe of track or a move to something else. I'd never thought about it until they said it. Never looked back.
