yeah... It's good question. Now hear dis!
Her's a little story I got to tell:P... Some time ago my friend started listening Prodigy. He's into Experience Era... When I had given him 'Rip Up The Soun System' he took liking this track. He was like: " hey man, this track is kool, particularly this female vocal!" Then I gave him "Android". What is interesting - he said that this vocal was "the same" as in 'rip up the sound system". What is important - his conclusion is very objectiv because he's NOT Prodigy fan! I told him that the name of 'singer' was Simone and I only knew about 2 track she has sang. But he was sure... Is it convinsin enough? Maybe not... but think about it!
