Interesting to see the both Calvin Harris and The xx have released apps to coincide with album releases and with the hope of encouraging more sales. This is a fairly new move by the music industry and the hope is that app sales and in-app sales of the album will encourage others to follow suit. A great article on this can be viewed over at Econsultancy
This is an interesting trend, one that will probably kick into life when Lady Gaga releases her next album. It was announced recently that her new album would be released as an interactive app and there are high hopes within the industry that this will be the start of a new approach to combat dwindling album sales. Only time will tell.
