I think total revenue is a poor way to measure the demand for music. The delivery of music recently became a lot more efficient now that songs can be downloaded online. It only makes sense that revenues would decline because a lot of the overhead that was built into the price has disappeared. It also doesn't help that for years the music industry conspired to keep the price of CDs artificially high.
