Spotify and Music Unlimited are both great music streaming services, but they have different strengths. Spotify has a larger library of songs and it's free to use with ads, whereas Music Unlimited has a smaller library but no ads and costs $10/month. Personally, I find the ad-supported Spotify to be good enough for my needs, but if you want to listen to music without any interruptions then the paid version of Spotify or Music Unlimited would be better options.
