2 It (Probably) Has Better Audio Quality
When you first look at the statistics for each service, you might conclude that Spotify has generally better audio quality than its closest competitor. Apple’s top audio quality is current 256kbps, while Spotify Premium sports music playback at a 320kbps bitrate.
But streaming via Apple Music might actually sound better in practice. That’s due to a variety of reasons, but most notably, Apple Music uses AAC, while Spotify uses MP3. While Spotify tracks stream at a higher bitrate, AAC is a less lossy codec. Not only that, but many of Apple Music’s AAC files are actually specifically Mastered for iTunes.
