British singing sensation Amy Winehouse may be the best musical marketing story since Madonna. In case you weren't paying attention to the music scene - or to the tabloids - over the last year or so, Amy Winehouse is the 24-year old singer, songwriter, (and the latest celebrity train wreck) who sings the hit "Rehab."

If you've heard "Rehab," or her other hits, you'd know her voice in an instant. And if you've ever seen the singer, I guarantee you'll never forget her. Covered in tattoos, with heavy eye-makeup and her trademark beehive hairdo, Winehouse is impossible to miss.

Sadly, her enormous critical acclaim and six Grammy nominations have been overshadowed by her public self-destruction and reckless drug and alcohol abuse. She's a favorite target of the tabloids and is right up there with Britney Spears and Lindsay Lohan when it comes to personal train wrecks. She's been described by People as "a perfect storm of sex kitten, raw talent and poor impulse control." Amy Winehouse makes Janis Joplin look like a saint. Let's just hope she doesn't share Joplin's fate.

What's any of this got to do with marketing, you ask? Consider the fact that in the cutthroat music industry, the chances of stardom are one in a gazillion. And when someone bursts on to the music scene like Amy Winehouse, you have to sit up and take notice. Her unique, soulful singing style, her distinctive looks and, yes, even her wacky behavior, create a remarkable brand identity. In "Sethspeak," Winehouse is a purple cow in a huge herd of me-too musical cattle.

Sure, she's immensely talented, but so are thousands of other performers. What makes Amy Winehouse stand out is that she's so... Amy Winehouse! She's carved out an unforgettable image and an unmistakable identity. Unfortunately, her personal turmoil is now part of that image but, if it doesn't kill her, it definitely keeps her in the news.

Minus the drama, marketers should learn from Amy Winehouse. Please don't run out and get a beehive wig just yet. But you do need to develop a brand. You need to be distinctive. And you need to determine your personal brand. Does Amy Winehouse stand out in a crowd? There's little doubt about that. But do you? If not, what can you do to grab your share of the spotlight? (Preferably, without breaking any laws!) What can you do to make sure that you're not singing the same tune as your competitors? Think about it, then go forth and build your brand!
