【明報專訊】Skyscraper, a very successful hit in 2011, occupied two positions at the BBC radio chart two weeks ago. The original version - performed by American actress-singer Demi Lovato - ranked 40th while X Factor winner Sam Bailey's cover of the song topped the chart. Music fans seem to hold diverse views, some claiming that Bailey lacks the "hooks" that make her a credible artist. One thing is certain: both Lovato and Bailey are special women.
