Mix: Microsoft, Etheridge, Orchestra, Market share

Microsoft has broken off talks with record labels regarding its planned subscription-based music service, Reuters reports.

Artist and cancer survivor Melissa Etheridge has released “I Run For Life,” a single chronicling her struggle with the disease, on iTunes. In October, 80 percent of the download price of the song will be donated to the Susan G.

Komen Breast Cancer Foundation and 20 percent to Dr. Susan Love Research Foundation.

The Milwaukee Symphony Orchestra has launched its own e-label, MSO Classics, created specifically for digital distribution of its recordings at online music services such as the iTunes Music Store.

This marks the first time an American orchestra has distributed works online under its own label.

A recent survey by research firm Piper Jaffray shows that the iPod and iTunes are gaining market share.
