Annie Lennox: 'Sing'

Question: when is a pop single not a pop single? Answer: when Annie Lennox rounds up "23 of the world's most acclaimed female superstar voices" for a charity record "to raise money and awareness for the HIV/AIDS organisation 'Treatment Action Campaign'". There. That's told us.

And so the great (Madonna, Gladys Knight, Celine Dion), the good (Shakira, Pink, Sugababes) and Fergie trade warbles for Africa, trilling about the strength of womankind over a nineties-sounding gospel-pop backing. Lennox's heavenly tones lead the way - fair enough, she organised the thing - but why is Madonna the only "female superstar voice" to get her own verse? Hmm. We reckon the adoption must have swung it for her.
