I used to use Spotify back in late 2013 to mid 2015 after my cousin showed it to me. It was fun finding out about new artists I have only heard mentioned, and on one occasion I re-found a producer’s (Submerse) works which was one of the biggest things Spotify’s ever done for me. I quit using Spotify around 2015 simply because I thought Soundcloud was just cooler.
Nowadays, I consolidate a lot of music through Youtube likes (I don’t have a single playlist), soundcloud likes, loose files downloaded from the internet, a history of purchases from Bleep, Boomkat, Bandcamp, and direct from labels, and a big collection of vinyl from various sources. All of these are still growing.
