Taglists is an iPhone and iPad app that lets you create and share playlists made up of music, videos, and photos that can be streamed for free by you and your friends. Just tag all the media with the same hashtag label and Taglists will generate the playlists for you. Want to enjoy these playlists via a different medium? No problem; Taglists lets you use Airplay or DLNA to play them on connected TV, A/V receivers, iPod docks, stereos, Apple TV and more.
We took a closer look at Taglists at Macworld 2012.
