I've picked up some artists I like by listening to what others like. I used to share an office and I had my XM Radio set up at work. I always let the office mate pick the tunes (no country, no rap) so I would get exposed to things I would not have sought out on my own.
Disco was great. I had the coolest pin striped suit with vest and disco pants. I hated to throw it away.
And we just went disco-dancing. Disco places opened up which kind of displaced smaller rock music venues. Cheaper, I guess, to hire DJs than live bands. Sad for the bands, but ... stuff happens.
During the Disco period, we were raising our kids, so didn't have a lot of spare time but did have fun when we could. We watched the Disco movie at a drive-in theatre with the kids too, I miss drive in theatres.
