Digital listening may be growing for younger drivers in the US, but AM/FM radio is still the most popular form of music access in the car. That’s according to a new study published by research firm LOOP via the Music Business Association. According to its survey of just over 3,000 respondents, 75% of drivers and passengers had listened to traditional radio in the car in the last week, compared to 38% who’d listened to CDs; 18% to digital music files; and 15% to streaming internet radio. The latter two stats rise for people aged 34 and under though: 28% apiece for digital files and streaming internet radio for that demographic. “We are happy to see new digital formats gaining ground as auto manufacturers make it easier for drivers to access them, while AM/FM radio maintains such a robust audience in the face of abundant change,” said Music Biz president James Donio.
