Some songs are put up as motivation to actually buy a song instead of download it illegaly. They put up the link to make you feel bad about downloading it that way.
yeah same thing happends with me. When i unintalled it a pop up kept saying "java could not open limewire) blah blah and would keep poppng up. So i just installed it again and dealed with it :/
If it has like 100 sources, its proly not legit. Try to find the same song with like 10 sources, or just try random ones till one works. The redirct ones usually arent viruses or my comp would be way more fucked than it already is.
you can tell those songs if the have over 100 sources, there's a bunch of the same song in a row, and they have a small file size, usually between 1000 and 2000 kb
