"Before I made this record, I was doing everything to try to get my music heard... I tried to lose weight and I was making awful music. It was when I started to be myself that the music flowed," the singer said in a report from BBC.

 Songs that compete for Song of the Year category includes: Meghan Trainor's "All About that Bass," Sia's "Chandelier," Hozier's "Take Me to Church" and Taylor Swift's "Shake It Off."

Petty, who considered it as a 'musical accident' and writing partner Jeff Lynne are said to have been receiving royalties since the issue was brought up in public.
