1. This presumes Spotify will still be in business in the next 10, 30, 50+ years. 2. This presumes 100% of the music collection is on Spotify. Personally speaking, 60%~ of the music I listen to ISN'T on Spotify. 3. This presumes music is only desired to be listened to when an available internet connection is available. Having to shuffle my media collections around whenever a third party went out of business or pivoted was such a massive headache that it was the inspiration for just managing my own media collections locally.
