I can format it to MP3, or ALAC, of FLAC, or whatever I like, and I can play them on devices that are made today, or 40 years ago.
But secretly I just use Spotify for it’s discover features, and then buy CDs of the albums I like.
Spotify isn't going anywhere.
Also, all the people holding onto their 8-tracks are definitely thinking they showed all of us. /s
It is still, for me, a cheaper and more flexible option despite licensing squabbles. It also gives me the opportunity to find new artists and give albums a few listens before deciding on whether or not they do it for me.
My views are USA-centric, perhaps licensing issues are more prevalent in other countries.
I don't want the plastic, the physical storage requirements, etc, of a CD. With digital I don't "own" the music, sure, but I've definitely lost more music in my life from scratched discs, people not returning CDs than I ever will through Spotify.
I guess there are many reasons for this, but mainly I guess they are simply victims of copyright.
I hear what you're saying, but the convenience of a vast and portable library is compelling.
