NPD made note of the rising impact of mobile on music listening. In another study released in February 2013, the research firm found that already 56% of US smart phone owners used their phone for listening to music. And of that group, 65% used internet radio apps like Pandora, above the 60% who listened to their own music catalogs and 30% who used on-demand services like Spotify.
What’s more, 39% of those listeners plugged in to smartphones to listen at least once per day. And 54% reported spending more time using their smartphone to listen to music than did so a year ago. Read the rest at eMarketer.
