Never pay for an inferior experience, but for £2.50 a month the experience of using Spotify instead of having to manually find, download, synchronise, and manage a music library is worth it for me.
“piracy is a service issue” - if a product doesn’t cost much and saves you time/effort then it can be worth paying a little versus essentially paying yourself less than minimum wage if it’s hard to pirate (depends how valuable your time is though!)
Fair enough, it works for me but not for everyone
