The ability to create branded playlists that are easy to listen to, but also unique enough to stand out from other similar products. I have not found anything so far that I dislike about this product. If you want something with great customer service, support, and quality work then definitely look into using activaire curators! We were able to use their services to help us develop our own playlist library for internal training purposes. They helped us choose songs that fit both our needs as well as those of our clients by providing recommendations along with suggestions for placement within each playlist.
