The Grammy nominated song recorded a huge success in sale to the tune of £100 million copies, and now Structured Asset is claimed it has right to the song which they alleged his a sample of their's since they have bought one third of the copyright from song writer Edward Townsend.
Structure claimed melody, rhythms, baseline, drum, harmony and every other things that makes both songs are very similar.
