If you like Arabic pop music (even a bit), then check out Raya Hilal.
I just keep playing her track "Jayee Ala Bali" over and over again! I am having to fight the temptation to buy the whole album from iTunes (it wasn't available on CD when i looked in Virgin or HMV), but i've spent far too much on music this month already…
She has a website: www.rayahilal.com, where you can listen to tracks in full, watch videos and generally find out about her.
