Common bugs

• Download stops at 90% silently — user thinks complete
• Crossfade breaks on track change mid-phone-call
• Playlist sync delay — changes on phone not visible on web for hours
• Bluetooth controls work for play/pause but not skip
• CarPlay fails on certain head unit firmware

Music apps should feel seamless. Any friction between tap-and-play is immediately noticed. Test every release with real devices and real headphones.
