I only keep music I like in my collection. It's not about trying to have the biggest collection... someone will always have more. It's about enjoying music you love and having only as much as you want, not what anyone else expects you to have. It's not a competition!
Roger that. I've been trimming my collection over the past two months, and currently have around two weeks of music.
At one point, it was much larger, but I realized I'd much rather have a smaller collection filled with music
I truly enjoyed than a larger one replete with songs I'd never listen to.
It's more satisfying this way, developing an intimate connection with the parts of your catalogue that
truly resonate with you.
Currently, only about 5% of my music is unplayed, and I'm constantly whittling that down.
I figure I'd rather have an in-depth collection of a comparitively small number of artists than
a shallow collection of a large number of random artists.
To the OP, my advice would be to make a smart playlist of unplayed music, and spend
the majority of time listening to (and deleting) things inside it.
With regards to listening to albums vs. individual songs, you don't have to choose the latter over the former.
I'm your age, and I'm an album listener.
It's really about taking the time to appreciate the ebb and flow of a record, rather than constantly hopping from this to that.
I imagine it also helps increase one's focus. Give it a try sometime. And for your own sake, stop watching television.
The overwhelming percentage of good music out there will never appear on TV.
