Style Jukebox caches temporary versions of your songs, as well as fragments of tracks locally on your devices.
The cache is designed to store tracks you've played before and may listen to again and fragments of the next songs in the Play Queue. The goal is to obtain a smooth and gapless playback of your playlist even in poor network conditions.
The cache uses only a small portion of your storage space and automatically clears it when you device is running out of space. You can also manually clear the cache from the Settings option.
