Dec 27, 2013 - Musio 2.0, an iOS music player, receives its first major update focused on design and usability. Musio is a new take on the iOS music player. Not only in terms of design and gesture-based interaction, but also functionality-wise. Musio leverages the iTunes music library that's already on your phone. The most important feature is the ability to manage a Queue, a highly demanded feature since iTunes received 'Up Next' on desktop years ago. Queue up or easily organize your music with Playlists.
