Since the September-release of his fourth studio album, Brass Knuckles, Mr. St. Lunatic, Nelly, has been trying to get things on the right track; this new version of One & Only, remixed with a little help from Polow Da Don, might do the trick. The emcee’s current radio single finds the highly successful rapper/entrepreneur using his signature sing-song flow to let his special lady know how much she means to him. At the risk of sounding PM Dawn-ish, Nelly adds a legitimate rap to the track, but its actually Polow’s grown-and-sexy production work that will make the ladies bring their two-step out on the dance floor. After that sexy don diva takes Nelly’s breath away, maybe she could leave a pen and a pad on the bedside table to encourage him to get back on the grind. This lovelorn cut may get a mixed reaction from the fellas, but to the girls, Nelly will always be their one and only.
