Akon admits he has plenty of other recordings they made together, but he doesn't want to hang on to them in case he is tempted to rework them - because his idol wouldn't have wanted him to release incomplete tracks.
He tells MTV.com, "Me and Mike worked on a lot of concepts before he passed. Hold My Hand was one of the records that was actually fully complete - the rest of the records are incomplete.
"They're just ideas, concepts, harmonies and stuff like that which the world will probably never see because I wouldn't want to put it out unfinished - so I might just burn it after this interview, 'cos I might just get tempted to do a remix!
"I know at the end of the day if it wasn't fully complete, I don't think he would see it released that way. I probably wouldn't ever put myself in a position to make that choice."
