The notion of better generated playlists is how SongCapsule drew my attention when I was looking online for third-party Apple Music apps. SongCapsule does live up to exactly what it says and does so with a clean, easy interface. However, my experience with Next quickly went downhill as I attempted to alter a setting that would prioritize lesser played songs. SongCapsule said it was refreshing my music library, which it then continued to do for the better part of an hour as SongCapsule ran in the background with my phone awake. After an hour, I closed SongCapsule and reopened it, only to be greeted by a loading wheel, which after another hour led me to believe that it would continue forever if I let it. I reinstalled SongCapsule and found the same issues again.
Even if SongCapsule will run successfully on your phone, paying $4.99 for a glorified shuffle button was only worth it to me because I had leftover gift card funds. As Apple continues to refine and update the functionality of their Music app and Apple Music services, it will be apps like this one that will quickly and increasingly fall into irrelevance.
