Just a few weeks ago, Gwen Stefani made her grand solo return with the debut of her island-flavored midtempo jam “Baby Don’t Lie“. Since then, the song hasn’t gained much attention and has only managed a #47 peak on the Billboard Hot 100, so its no surprise Gwen is ready to move onto the next. Nine years after topping the charts with “Hollaback Girl,” Gwen rekindles the flame with her fellow The Voice coach Pharrell Williams on her brand-new single “Spark the Fire“! “OMG, OMG, I’m back again / Original feel good is what I defend / I’m a believer, no I don’t pretend,” Gwen declares over Pharrell‘s signature bubbly production. The song is oozing with playful energy and Gwen sounds right at home in the addictive, chanty chorus. I’m not totally in love with this right off the bat, but the more I play it, the more I found myself jamming out. Without a doubt a grower but I still feel like something is missing. Hmmmm. What do you guys think?
