It depends on what you're auditioning for. It's more important for the people who are casting to be able to see you in the part you're up for.
Many "now-famous folk" have auditioned with original or unconventional material. So, history shows us it can work succesffuly. I wouldn't be afraid to use an original song, or a "non-theatre song," unless it doesn't fit a the part... or it's such a "showy" song (for whatever reason) that it outshines the performance. Everyone will be asking you where you got your song, and they won't be thinking about your performance. Not a good thing.
But don't be afraid to sell yourself to your best advantage... and go a little outside of the norm. It's important to make SURE it's to your best advantage, though.
EDIT: Oops! I took "material" to mean SONGS, too. But the same principle applies to monologues. And actually I can give you MANY examples of actors I know who have landed parts with original monologues... or non-theatre monologues (books, poems, letters, etc.)
