Yes brother it is limited to one area! Look at Yalemwork, eventhough she is good singer,she's music is limited to one or 2 musicians song! For me this can not be perfect method to identify one from the other.The judges should give different musicians work and test them. How can we judge she is perfect by offering her only one or two musicians music? There are a lot of methods to test them! Fana Lamrot managing team should take corrective measures on this issues.
