Recently, we have made changes to the way audio files are handled through our store. Previously, audio sales would provide a downloadable MP3. This feature is being phased out and replaced with an audio streaming option. This means you won't have to download or keep track of your MP3 files. You can now stream them directly through a web browser (or the CE21 Mobile app). Audio streaming products can be saved in the CE21 mobile app for offline playback.
