Love the Godspeed reference in your youtube video. Have you ever delved into music that isn't necessarily ambient but incorporates ambient into their music? I have a few suggestions. You talked about pop and I thought it'd be cool to show you some pop artists that incorporate ambient into their music.

Felt Mountain -- Goldfrapp's debut album. It's a cross between baroque pop and ambient with elements of trip hop. It has some really great ambient atmospheres.

Fever Ray -- Full blown ambient pop, elements of drone as well
Also are you a fan of Tim Hecker? He's an amazing contemporary ambient artist.
