You can let Lexicon fill in your missing track info like Genre, but sometimes it doesn't find anything.
Lexicon looks for your tracks by artist & title. So it is important that information is correct and clean. Often there is incorrect or messy information in a title that will cause the search to fail. So make sure your artists & titles are neat and correct!
One way to quickly clean your titles is by using Smart Fixes.

If you still don't get any results, maybe your track simply doesn't officially exist. Bootlegs, unknown remixes or unreleased tracks will most likely not give proper or any results.
