- Online services are unreliable: They can go offline at any minute, go out of business, ban your for any reason (including from automated ban systems tagging you for "suspicious activity" if you login from different counties, use vpns, etc).

- Their catalog of music can change: Songs can be deleted at any time.
- Better performance: searching local storage is faster, skipping around is faster, better battery life by not needing to power up the 4G radio/wifi.
