AceShowbiz - Lauryn Hill has angered her fans for the second time in a month, after keeping an audience waiting for three hours at a comeback concert and changing her songs beyond recognition. The reclusive singer was due to take to the stage in Atlanta, Georgia at 9 P.M. EST on Friday night, January 14, but she didn't begin her performance until midnight.

And the crowd at the Center Stage venue was unimpressed when Hill finally began her set - the singer reportedly declared she was tired of "playing the same music night after night" and performed several unfamiliar versions of her hit songs. One fan told the Sandrarose.com blog, "Nobody could participate because NOBODY knew the music! Everybody was looking around like 'What Song Is This?' "

"It was new music completely. The lyrics were the same, but you had to be on ecstasy to follow the music!... Everybody just stood there with their arms folded. It was a waste of money, and a waste of time. If she did another show in Atlanta, no one would come!"

A number of fans booed, while others walked out, according to the unnamed audience member, who adds, "They didn't walk out - they stomped out!" Last month, Hill, who is touring small venues across the U.S. as part of her musical comeback, annoyed concert-goers at a show in New York by keeping fans waiting for almost four hours and telling them she was "worth the wait".
