It was amazing to me that all of a sudden I was hearing my music on the radio and coming out of cars.

Music is one of those things that make us feel a little less alone in the world.

I'm actually not an exhibitionist at all. When you get onstage and you get under the lights playing music I feel more hidden and more alone than anywhere else. You hide behind your music and let your emotions come out through the music.

Glasgow's not a media center. When you're there when you're hanging about you feel quite detached from musical movements or fashions or anything like that. You do feel quite alone in a good way.

I've performed solo for 20 years now but I don't do much of it because if you only play alone you go crazy and out of tune and play foolish music.

You'd think I'd have been happiest in my life playing music in front of 50 000 people at Gillette Stadium. But let me tell you it's an odd feeling to feel alone in the spotlight.

What does it mean to not be alone? I've approached that question through music technology writing and other means.

As for style there is something about the way musicians dress-they seem to be able to create their own world within their fashion alone.

We talk a lot on 'Biggest Loser' about how fitness is a natural antidepressant how it burns off stress. What I like about running is that it gives me time alone. I'm always busy with people at work with my kids. I love getting out for a run by myself and just listening to my music.

The music industry is a strange combination of having real and intangible assets: pop bands are brand names in themselves and at a given stage in their careers their name alone can practically gaurantee hit records.
