While most music-streaming services focus on popular music, IDAGIO’s mission is to make classical music just as accessible. “The complete set of classical music on your phone. That’s IDAGIO,” says communications director Birgit Gehring. The $10-a-month service—the brainchild of music-industry veteran Till Janczukowicz—offers more than 2 million classical tracks, which can be sorted by composer, conductor and soloist. There’s also a free version with ads, and playlists for new listeners who are just getting acquainted with the genre. —Emily Price
