Sydney Harwin Addict -
Wait, let me check Sydney Harwin's background. She's an Australian singer, songwriter, known for being part of The A-Sides, which was formed in 2004. They had some hits, then she left the band in 2009 to pursue a solo career. She released an album "Sydney" in 2011. Maybe "Sydney Harwin addict" refers to someone who's really into her music. Or could it be a play on words? Sometimes people use "addict" to mean a fan. Like, "I'm a fan, an addict of their music."
