Gracenotes only works on full albums and not on individual tracks. The way it works is it looks at the table of contents of the CD to get the number of tracks and time of each track and what order they are in. This creates an almost unique "fingerprint" of a CD because it is rare for two or more CDs to have the exact same number of tracks with the same song lengths in the same order.
So as you can see, a single song is not very unique and so databases like Gracenotes are of no use trying to automatically look up single tracks or randomly burned "mix" CDs.
