Music is different. Music can (and does) exist without DRM and will continued to be produced whether the RIAA pushes DRM or not. I think the main difference is that music is an art. Musicians are artists who often produce music simply because of the their love for the artform.
FWIW Steve Jobs' point is that 90% of the music sold today is
already sold without DRM, on CD. Unless the RIAA is going to stop making new CDs it is somewhat pointless to place additional restrictions on digital downloads that are not already on CD.
I do find it a bit disingenuous that Steve Jobs didn't even mention movies/tv shows/software in his article, but there is one fundamental difference between those other forms of content and music.
Expectation.
Since the invention of the Walkman we expect music we purchase to be portable and go anywhere with us from home to car to bike, etc...
The cassette made music that was already omnipresent portable, and the CD took that a step further. All without DRM.
We don't yet have that expectation for video content or software. You don't expect to be able to play a VHS tape anywhere or watch a Beta tape on your DVD player. You also don't expect Windows software to work on a Mac or the latest Xbox 360 game to play on your Wii.
This expectation is bound to change over time, but as Steve Jobs has already said more than once the experience of listening to music and the experience of watching TV are very different.
How many of us listen to music while we _____? How many watch TV?
