Try varying your search ... not only using music type search. And vary the search criteria & you may get more results. Also try using LW at different times of day. Different people come & go over a 24 hr or week or 2 week period.
I'm not sure about full length tunes, but I'm sure they're out there. You could also try searching for albumwraps. See
How to Downld whole albums & Albumwrap.
