The power of music is still most under-appreciated.
Try to imagine today's "tech revolution" without music.

Computers in the home would not be 1/2 as fun without mp3s & videos
No one would need high-speed internet from cable companies for downloading
No one would buy CD burners or blank CDs.
Tower Records would be open.
Apple Computers would be a division of IBM.

Doesn't it feel like someone owes rock music a couple of billion dollars?
