In case you weren't already aware, The Saturdays have a new single out this week, the deceptively catchy '30 Days'.
To celebrate the release, we've asked each of the girls to tell us about their favourite song at the moment that isn't their new single.
Nelly Furtado: 'Big Hoops (The Bigger The Better)'
"Nelly is totally back on top with this new track - the beat is what really does it for me. The lyrics are a bit out there, but the chorus is massive. It's a good one for us girls to get down low in the club. In my books, the bigger the better is always the right answer - especially in terms of my jewellery, of course!"

Starboy Nathan: 'Who Am I'
"I absolutely LOVE this tune, and Nathan is such a top boy. I like the sentiment behind the song. I've seen him perform it live and he absolutely smashes it."

Demi Lovato: 'Give Your Heart A Break'
"I absolutely love Demi's album Unbroken and this is my favourite track on there. I can really relate to the lyrics - and you believe every word she says. Her vocals are really powerful but at the same time really emotional."

Wretch 32 feat Ed Sheeran: 'Hush Little Baby'
"A wonderful collaboration from two of Britain's freshest young artists. Although they both hail from separate genres, together this very popular rap/singer-songwriter style works remarkably well for them.
"When I first heard the title I was expecting the lullaby that I often sing to my little daughter Aoife to help her sleep! Obviously this is not the case. The video is also very clever with loads of things going on."

Emeli Sandé: 'My Kind of Love'
"This is my favourite song at the moment, and from my favourite album as well! Her lyrics are so powerful - you can tell she is writing from experience. The way she sings really hits you. There's so much dance music out at the moment, it's nice that this is so different."

Not a bad selection, we're sure you'll agree.
