well I was speaking to a few artists that are in the music biz and they told me a simalar story. they sampled a song from puerto rico (they thought it was an childhood song that belonged to nobody) and a few months later, a little old lady approached them and said "my husband wrote that song and now you have to pay me". well, the brothers went over to thier record label, which owned the songs and they (the record label) had to pay her. so, I think the beasties will be cleared of this thus making DEF JAM and Capital the ones that have to pay.
here is the sample/lyrics they used:
