I'm 56, I don't own a CD player.
I do buy T-shirts if they look good and I can wear it in the high street or pub without looking odd, stand out or edgy.
There might be mileage in producing CD like cardboard inserts with a personal userID and link to a download area containing special editions and bonus tracks not available on Spotify. People can then visit the area, sign in with their userID. Then either add that to their Spotify app as a download or burn to a CD.
However, the point of having free sharable music, is that your audience grows exponentially through word of mouth and then people come to your gigs, buy t-shirts and tickets. Important now that hardly anyone listens to the Charts...
