your Best bet to get what you want is to download one of the songs your searching for that has a higher Score (score=how many people have the same song)

the score is your friend unless you know what you want.

another hint is to look at the file sizes... if your trying to get a zip file and its small in size, be weary unless you know that the zip is something small. some programs and other things are huge but bogus files usually arent.
