One example: On Android, I bought an SD card (because my internal storage was too small to host my downloaded library, for offline listening on airplanes). I found that when I rebooted, every single time, it would redownload all 11G of my downloaded songs. Turns out, the Spotify service starts before the SD is attached and their program has a bug. I sent them the Stackoverflow link to delay the service. Support wasn't interested in helping me. My fix was to get a phone with larger internal storage.
