"[It's] more than I expected by a long shot," Grey told AOL Music, discussing the song's success.
Born Holly Brook Hafermann, Grey released an album under her birth name in 2006. It wasn't a huge commercial success, but the 25-year-old has since made her name in the pop and hip-hop worlds. While she's not as comfortable with the latter, she's hoping to attract listeners interested in all types of music.
"I didn't work on hip-hop until a year and a half ago," she said. "Hip-hop is like a new thing for me, a new adventure. I think with pop music, a lot of times, people will start with a guitar or piano and write a song that way. With a hip-hop record, you start with a fully fleshed-out track. ['Love the Way You Lie' producer Alex da Kid] gave me track after track, and I just wrote hooks, and we picked the ones we liked, and I wrote verses. It's a little different writing style, but I like challenging myself to do different things."
On 'Invinsible,' due out this fall, Grey is looking forward to showcasing her varied musical abilities.
"It's really diverse, because I have elements of hip-hop, but because I come from a very different background of music, it has rock and kind of cinematic stuff," she said. "It's a little bit like experimental hip-hop/pop."
