The whole offline / no data experience is absolutely terrible if you live anywhere like Canada where mobile data rates are small and expensive. The #1 complaint I've heard about Spotify for years is "I set it to not download music on data then didn't notice I was listening to a new playlist and now I'm out of data till next month". Also taking public transit like a subway without cell service was a pain. Hold on, let me open the settings in advance and flip the offline switch so I can keep listening to music on my commute. Ugh.
