I am a happy Spotify user, was interested in Apple Music—streaming all my music in the cloud + Apple's catalog = win—until I saw how deeply flawed the execution was. But I've noticed lately that Spotify, Evernote, etc., are frequently interrupting my workflow with badges, notifications, interstitial screens, pop-ups, etc., to try to entice me to upgrade. I understand why, but this type of interruption marketing is hostile to their users and builds customer resentment, not upgrades. These breaks in my workflow make me resent the products and the growth hackers behind them. Most vile is Spotify and its obnoxious badge notification on the dock which cannot be turned off—and which always points to a list of nonsense, e.g. "Some random playlist has added 3 tracks last night." I am more interested in first party apps nowadays since they never push ads and promotions in my face. I just hope Apple can get better, and fast, at making great innovative cloud apps.
