As an successful pop-soul singer, Amy Winehouse inspired many female artists and bands alike who followed in her footsteps years later. But it was recently revealed that an unexpected group of brothers were the reason that the 'Valerie' singer herself first found music.

Hanson -- yes, as in 'Mmmbop' -- were idols for Winehouse as she was growing up as a teenager in north London. Sadly, the brothers had no idea that that they'd been a guiding light for the singer until after her death. "I didn't know that she was a fan," oldest brother, Isaac, tells WENN.

He continues, "It is really, really tragic when you see someone like Amy Winehouse. You go, 'She had a really great voice. She's got a talent that is unique and powerful...' She had this soulful passion and intensity. It is tragic to see people not be able to fully deal with that inner turmoil, which unfortunately, most artists, including myself, have. You have this tortured element within you and you're throwing yourself out there emotionally."

Isaac, now 30, was just 16 when he and brothers Taylor and Zac found ultra-worldwide fame with their debut single. In just over a decade, Hanson saw the many ups and downs of the industry, which makes it somewhat easier for Isaac to relate to Winehouse and (some of) the struggles she went through before her recent death.

"God rest her soul," Isaac adds. "I feel so bad for her that she was not able to reconcile whatever was going on inside her... It sounds like there were so many lovely, lovely elements of who she was and unfortunately there were some darker elements that clearly got the better of her."
