Another snippet that I have just thought of is the watery guitar part in Busta Rhymes and Janet Jacksons "what's it gonna be?!"
Will try and find out out who is responsible for these sounds. I'm sure there must be a core of widely used session musicians.
The part I am on about starts @ 23 seconds.

I DONT SUPPOSE ANYONE HAS THE ACTUAL ALBUM THIS IS ON AND CAN CHECK THE LINER NOTES TO SEE IF THE GUITARIST WAS CREDITED?
