Soldato
These days Spotify for my day to day in the car and on phone, PC has a mp3 / flac collection that I've been building over the last 20 years.
Owning music with iTunes, isn't it a bit of a misnomer?
The MP3 files themselves are purchased elsewhere, stored on my PC's SSD and also backed up to two further external drives. They are collated in iTunes for use with the Classic (and I'm quite attached to it's interface), but not bought through iTunes itself.
