If you’re like me, you spend a majority of your night lying awake in bed wondering aloud: “What are the Spice Girls doing with their lives right now?”

Well, Victoria‘s busy being flawless and pushing out babies named after magazines and fashionable jeans. Mel B is busy being pregnant, Emma‘s being mommy-like and hosting radio shows, and Geri‘s busy getting her biddies out with both an upcoming bikini line and new music. (Which of the two will burst out first? Who knows!)

As for Melanie C? She’s about to release her fifth studio album, The Sea.

After the quiet release of the (very good) “Rock Me” in June as an official tie-in with the 2011 FIFA Women’s World Cup (keeping it Sporty, always!), the singer has come rocketing back with the (amazing) official lead single from the campaign: “Think About It.”

Recorded with Adam Argyle (who also worked on Melanie’s last two studio albums) and Danish producer Cutfather (Kylie Minogue, The Wanted), “Think About It” might best be described as a perfect mash-up between “Raise Your Glass,” “Last Friday Night (T.G.I.F.)” and “Teenage Dream,” meshing the gritty guitar verses of P!nk and Katy Perry‘s rebel revelry anthems and mixing them up with the masterfully lush, dreamy choruses of Perry’s 2010 summer smash.

Is it the most original song? No, not particularly–it’s essentially the greatest parts of Teenage Dream. But one listen to those gorgeous, soaring vocals and pulsing summery synthesizers and you’ll likely forget that you probably heard this one playing on the radio before.

The Sea will be released on September 4. (iTunes)
