My husband laughs at me for doing this. I don't know why I do it.

I was so sure that this is @bassinyoface but ...

Cause youre focusing less on sound rather than sight.

Not to see, it's to focus

The inability to do anything that requires concentration while listening to music is "discom-bebop-bulation!"

I do it because I don't want to pull up with music blasting. I think it's kinda annoying, but that's just me.
