Sounds like your trying to download a new or popular song. I don't know how it works, but basically if you see the song your looking for and there's a bunch of'em all with at least 20-100+ sources and they are the same file size (or two file sizes) and the same duration, chances are if you download one and it doesn't work, the rest of'em won't. What you have to do is try searching for just the song and not the artist. You get significantly less results and generally only 3 choices with almost no sources (sometimes you will get nothing or just results of stuff your not looking for), so it'll take me like 20 mins. to get the song, but it's usually the real thing. The other thing to do is look on the list for the ones with a different file size. They usually are at the bottom of the list with like 5 sources. Not saying songs can't have tons of sources, but they tend to get lost in all the fakes. Hope that helps.
