I basically did exactly that.. I canceled Spotify and pretty quickly bought tons of stuff. Check my "collection" at Bandcamp: https://bandcamp.com/amatecha
In a casual manner, I allot myself ~$15/mo (or more) to buy new stuff on Bandcamp. As you can see, it's going nicely and I have a ton of music from my favorite artists, also stored permanently on my NAS in mp3 and FLAC formats.
I'll step out on a limb and say that the kinds of consumers I'm talking about think that NAS is a rapper and think that FLAC is a short way of talking about the company with the talking duck. :-)
