The other 80% of the music is what I'd like to talk about.
Whenever a new song came on, I thought to myself, "What is this DJ smoking?" I would then look around the bar, and see people realize what song was on and start laughing and singing along. At first glance, this seems like a good thing, right? Not so fast.
The music that was playing was not good music. It was not music that was played with the expectation that it would be heard by someone that actually thought it was good music. It was music that is commonly refered to as a guilty pleasure.
Look, just stop it already. If it's bad, it's bad. Stop trying to justify listening to bad music by doing it "ironically", and just admit that you enjoy it for what it is. If you like it, great! Listen to it if you want, just be honest about why you're listening to it. You'll be surprised how liberating it is.
Nobody thinks Abba is good music. But that doesn't mean you can't enjoy it. It's all about The New Sincerity, folks.
