I doubt that Katy Perry will be selling many records in five years. In 50 years, she will barely be remembered, at best, and people will still be buying Coltrane records.

all the vinyl I got rid of in 1994 when a relationship failed and I decided to move out.

I try not to cry, or even recall that my husband discarded all of my albums some years ago. Damn.
(I moved out 6+ years ago.)

The turntable is a high-end Technics and yes, it is tied into the stereo. Vinyl rarely skips if you keep them in good condition, but CDs are prone to getting boogers and man is it annoying when they go into a track repeat.

I respect your choice.

This doesn't surprise me, it was expected. Two reasons immediately come to mind:

1.) Young people, the people consistently most-likely to buy new music, are now more likely to buy single tracks of digital music rather than full albums.

2.) They're also more likely to have moved away from music purchase altogether toward subscription-based music archive access services like Spotify and Slacker. Why buy anything when I can pay a $8 subscription fee and have access to better than CD-quality archival-copy of virtually everything ever recorded a my fingertips on-demand on computer* and mobile. Another $200 buys a compatible car-stereo unit.

*-To make some sense of this, it's important to know that my home PC is a full multimedia center with hi-def surround sound and 1080p TV-tuner. My computer is my stereo, TV, telephone, videoconferencing-tool...and it's equal to the top-of-the-line models of any of the above. I've got about $5K into this computer and components.

What created the whole music industry as we know it today was the creation of the teenager-driven economy. It is not what it used to be.
