This debate has been hashed out hundreds of times on this forum. Not sure why we need yet another thread on this.
In sum, the following are the pros and cons of each:
Spotify:
Pros -
- The best playlists for both what you already like and for music discovery.
- Clean mobile app.
- Very wide cross-platform operation on every OS and Spotify Connect.
Cons -
- Fewer exclusives.
- Sound quality isn't as good.
- No Apple Watch app, no AppleTV app.
Apple Music:
Pros -
- Better sound quality, especially if using AAC-compatible bluetooth headphones or speakers.
- Exclusives and radio (if you're into the genre's they target).
- Full integration into Apple ecosystem (HomePod, Apple Watch, AppleTV).
Cons -
- Bad playlists for music discovery, and narrow range of genre-specific playlists.
- Clumsy mobile app with giant text, unpredictable behavior with syncing and offline downloads.
- Family plan requires all members to share an App Store credit card.
