My music tastes are unusual, and to me, much more interesting than anything likely to be found on Sirius, or iTunes, or streaming services: medieval music, "pure drop" Celtic trad, eastern European folk, classical, Appalachian, klezmer. I have hundreds of CDs, some by local musicians. So if I go to a concert an hour away and support the musicians by buying their CD, why should I not be able to play it on the drive home? This doesn't matter to Taylor Swift fans, but I'm a musician. I take music seriously.
Musically, I'm in a similar place, with classical, folk, and contemporary music from all over the world in Arabic, Hebrew, Ladino, Turkish, Persian, English, French, Gaelic, German, Greek, Hungarian, Italian, Macedonian, Portuguese, Spanish, Swedish, Norwegian, and Finnish, Tamashek, and I don't know how many other languages from Asia and Africa.
For the past 20+ years, most of my music purchases have come from Amazon, as MP3 downloads when possible, CD if not, or if the liner notes are especially useful. When my wife and I go to live music performances, we often buy CDs directly from performers.
The "too much time required" argument is a red herring. As soon as I get a new CD, I rip it, a task that, once started, requires no intervention on my part, so my net labor cost is less than a minute per CD. As I acquire more music, it gets copied to a USB flash drive, again, a task that requires a few seconds of my time to initiate. Digitizing from LPs is the only conversion that required a significant amount of time, mainly to go over each track with a sound editor to remove pops and clicks. Excluding LPs, over the past 20 years, perhaps an hour of my time has been required to digitize hundreds of CDs; the incremental cost for ripping a new CD is negligible.
