I don't normally listen to too much mainstream music but.... Emeli Sande has such an amazing voice!
I'm currently listening to her album 'Our version of events' and I really like it. I'd say it's up there with my love for Adele, Whitney Houston and Madonna! It's got a good edge to it aswell though!
I also think that Emeli has got a good style to her, she's edgy yet feminine, which I really like!
In all honesty i've just fallen in love with her voice, I especially like the song 'heaven' It reminds me of the old school house music that I love! Good to dance round the house to!
I'd advise you to check this album out if you're looking for a strong vocal in music!
