Blu Cantrell and Sean Paul - Breathe (instrumental) B minor
Dr. Dre and Snoop Dogg - Nuthing but a G-thang (acapella) C# major, so A# minor
UPDATE - thanks for previous likes, downloads and plays
Blu Cantrell sampled Dr. Dre 'What's the Difference' in 'Breathe'.
So now I put Dr. Dre and Snoop (pitched up one semitone) back on top of Blu.
Send reverb on vocal, small timing corrections. Included parts of Sean+Blu's rap to reveal source.
