A little while back I recall reading an article about Robert Fripp (guitarist for King Crimson) and his ongoing battle to stop his previous 
label from selling his back catalogue and intellectual properties digitally as they never were a part of his original contracts. Today I came across this article about a similiar proceedings between Pink Floyd and EMI. It looks to me that the power in this business is migrating to reside in the artists hands.

More bad news for EMI:

(Updated) A UK judge has ruled that a mid 1990's contract between Pink Floyd and EMI that includes maintaining the artistic integrity of each album release does not allow EMI to sell single tracks on iTunes and other online outlets. But the court stopped short of making EMI pull the tracks down.
An EMI statement said: "Today's judgment does not require EMI to cease making Pink Floyd's catalog available as single track downloads, and EMI continues to sell Pink Floyd's music digitally and in other formats.

"This litigation has been running for well over a year and most of its points have already been settled. This week's court hearing was around the interpretation of two contractual points, both linked to the digital sale of Pink Floyd's music. But there are further arguments to be heard on this and the case will go on for some time."
 

Make sure that you clearly state your position on ALL possible streams of income when negotiating contracts.

You never know what the future might bring .
