Nelly Furtado's 'Big Hoops (Bigger the Better)' is inspired by her memories of being a teenager.

The lead single from her upcoming album, 'The Spirit Indestructible' is in part a homage to her favourite fashion accessory, hoop earrings, but Nelly revealed it also reminds her of being 14 years old and wearing her sister's jewellery.

She said: ''I think music can tap into a lot of powerful emotions, and I think in the studio on 'Big Hoops' I tapped into a really powerful memory of being 14 years old, completely in love with hip-hop and R&B along with all my friends, and putting on my sister's big hoop earrings and heading down to the mall to hang out with my backpack and jeans.

''[Back then, I was] writing rhymes and hanging out and freestyling on the corner and feeling famous already, even though I clearly wasn't at 14.

''But I felt [famous], and I think when you're that age, you have your inner gumption already. So 'Big Hoops' taps into that power.''

Nelly also revealed she wrote the song to tap into what she believes is missing in music, ''rawness and power''.

She added to MTV News: ''The state of mind I was in, I was actually listening to a lot of different music a few weeks before,'' she continued. ''I think I was listening to Odd Future or something, and I was inspired by how dark it sounded and how heavy and visceral and how it made your blood feel things. And I just thought, 'Wow - that's really missing in music. We're missing that rawness, that energy and that power.'''
