EMI and Groovebug’s iPad app for Blue Note Records was downloaded 30k times in its first five days on Apple’s App Store, according to Blue Not president Don Was.

He was speaking at Billboard’s FutureSound conference about the app, which was one of the first fruits of the OpenEMI initiative.

Was didn’t say how many of those people subsequently signed up for the £1.49 monthly in-app subscription for paid access, though.

He did praise the Blue Note Spotify app, which he said generates an average of two-and-a-half hours listening, versus five minutes at a time for the average Spotify app.

“It’s mysterious to me how they did this. The way it flows you really get the feel of going through a bin of vinyl – the way information is released to you, the sense of discovery as you cross reference all these musicians who played on all these records,” said Was. “I think it’s a radical Spotify app and the results we are getting bear that out.”
