Because of things like iTunes and streaming and social networking, it's destroyed music. It's destroyed the motivation to go out there and really make the best record possible. It's a shame.
On 'Metallica,' I recorded six or seven different guitar solos for almost every song, took the best aspects of each solo, mapped out a master solo and made a composite. Then I learned how to play the composite solo, tightened it up and replayed it for the final version.
