whats the deal with these 20min songs with no music

[djburns79]

I started seeing these pop up alot now. Where you download a song say 4258kb it normally is a 4 to 5 minute song. Now you download then I put it in my win player and it says anywhere from 15min to 23min. Whats the deal? There is no music and its usaully newer songs like a heavy rock bands cover of a 80s tune where they had puppet of reagan and others in the 80s. I also notice that the number on the left which is usaully between 50 and a 100 its like 250 or 400 or some chit. and u scroll down and its still high. Anyone know if its a spyware or some ad thing. I also have the newest version of limewire. Because I was getting those redirects.
