Universal Music Group’s digital boss Rob Wells has weighed into the debate around artists keeping their new albums off streaming services like Spotify.

In an interview for Topspin CEO Ian Rogers’ This Week in Music web show, Wells criticised the assumption that “you’re not going to earn the same money” from a Spotify stream as from an iTunes download. “But what if it’s incremental revenue, not cannibalistic revenue? So this is all additional money.”

Wells went on to suggest that the music industry “should be supporting these services because what will fix this remuneration is scale. That’s all. It’s just scale.” He also had sharp words for artists like Coldplay, whose new album Mylo Xyloto is not available to stream.

“I do find it quite irritating when bands decide they don’t want to do this… As an industry we should be showing some sort of solidarity, because there is a wave of customers – the demographic on these services is between 16 and 22-24 – and the disappointing thing about a band like Coldplay doing this is that consumers who are on these services are not going to turn away and buy that album on iTunes. They may miss out.”
