"It’s ‘Music’ (the track) that I play at deejay sets the most, albeit my own slightly tweaked version. I love it and never tire of it and think that what she and Mirwais accomplished together was fantastic! I do get a great response when I play Ray of Light however, even though it’s not a bad-ass demented techno tune, my favourite style to play. This is probably because of general goodwill and fondness towards her from my audience. Everyone has a good memory to go with that song." [...]

"I had to listen to the ‘Music’ album tracks on which I’d participated the other day for something that Warner's had requested. I cringed when I heard ‘American Pie’. A song that truly deserves it’s place at the top of the ‘worst-ever-cover-versions’ roll of dishonour! What were we thinking?
But ‘Runaway Lover’ sounded so good. It has stood the test of time very well and has a superb vocal from M. She very much sculpted the way that it sounds on the album. I was a bit spaced out during that one I recall and Mark (Spike) Stent did an excellent mix.
What really got me thinking is that the song ‘Amazing’ did not ever reach its full potential. i would love to mix that one again. There are elements that didn’t make it to the final" [...]

"there are vocals that she did in the late nineties that have particular strong emotional power. Not all of it released. Much has been written about her dramatic activities but she is capable of mining greater dramatic depths in her vocals than most singers today. It just isn’t always in the obvious way. You have to be open to it. Plus there is always a lot of ear candy too. That combination is part of the fascination.
Interesting the you mention a reworking of ‘Drowned World’. That could be very good, I was speculating on that just the other day. The original demos sound magical and golden. But I’d only do it as an exercise in musical possibilities for myself. M doesn’t look backwards readily and there are, naturally, Warner Bros considerations which are way above my head." [...]

"But although there is a lot of unreleased material, some of which is exceptional, the question of its release can only be answered by her. And she has a lot else going on in her world at any one time! I always look at it this way, you cannot fault her sense of timing and change so there’s not much pointed in trying to second guess her. She’ll be going strong for another 50 years, what’s the rush?"
