All the time.
It started with my parents' vinyl collection. I would turn the speakers towards each other and sit in the middle. The Beatles. Elton John. Many more that I've long since forgotten. I loved sitting between those speakers, getting that pure stereo vinyl sound.
Later, I got a cd player and headphones. Also, a minidisk player? I think I still have it somewhere... I would always be plugged in on long car rides. I would always have headphones on while doing my homework. This was the era of *coughNapstercough*, and even on my very slow home dial-up connection, a whole new world of music was open to me.
I didn't discover radio worth listening to until I got my first car, a '93 Ford Thunderbird. That's about the time I started listening to the now defunct WFNX, a station which shaped many of my listening choices at the time.
During college and after, I slowly stopped really listening to music. Listening. Over and over to songs I loved, memorizing every detail. Somewhere along the road, that stopped.
Maybe I don't have the time for that kind of focus anymore. It's sad, because to truly learn about it, you have to listen. Listen close, listen carefully. Hear every detail, then step back to get the whole picture.
I'm sure my hearing won't love the headphones I bought myself a few months ago, but now I'm trying to put aside time to sit and listen. It's amazing what you hear when you listen close. The sounds become more real, almost tangible. A whole new world opens.
Take the time to listen.
