What's more, he suggested that mobile companies have much to learn from Apple, despite being critical of and iTunes in the past, adds MacUser.

"For years now, Warner Music has been offering a choice to consumers at Apple's iTunes store the option to purchase something more than just single tracks, which constitute the mainstay of that store's sales," Bronfman said. "By packaging a full album into a bundle of music with ringtones, videos and other combinations and variation we found products that consumers demonstrably valued and were willing to purchase at premium prices. And guess what? We've sold tons of them. And with Apple's co-operation to make discovering, accessing and purchasing these products even more seamless and intuitive, we'll be offering many, many more of these products going forward."

And the iPhone and iPod touch shows that approach can be made to work on mobile platforms, he said.
