It's getting harder to categorise rock and metal bands says Hale

Halestorm’s Lzzy Hale says metal and rock bands can’t be pigeonholed anymore as the lines between genres and sub genres have become blurred.
Hale, and guitarist Joe Hottinger, also discussed the Grammy Awards – an honour Halestorm have on their rock mantelpiece following a 2013 win for ‘Best Hard Rock/Metal performance.
In an interview with Russia’s Classic Rock, Hale says: “I think it's getting harder and harder to categorize anything anymore, just 'cause everything is… there's so much out there, and it's so broad. If you say 'rock music,' it's so all over the place. And same thing with metal — same thing. Depending on your spectrum of heaviness and your opinion of it, it's getting harder and harder to categorize."
She continues: “We know a lot of the people at The [Recording] Academy [which oversees the Grammy Awards] now, and it must be such a hard job to try to narrow all of that down and choose the best one. So, yeah, there's always things that, like, you personally are, like, 'Ah, I would have voted for that. I would have done that.' But, you know, at the end of the day, it is what it is.”
Continuing on the theme of the Grammy Awards, Hottinger reveals: “It was interesting to see who won. I'm glad everyone who wins wins. You never know how it's gonna go. It was neat that Sevendust got their nomination, and we were pulling for them. 
“Also in the same category, there were some hometown guys, August Burns Red; it's cool that they got nominated. But we know the Ghost guys. They're nice, and we're happy for 'em."
He continued: "I really like Alabama Shakes; I think they had such a cool record. It's just strange that they won 'Best Alternative' record and then they win, like, 'Best Rock Song' too. To me, they're more of an alternative band. It's a great record — I love it — but it would be cool to see hard rock a little more represented in [the] 'Rock' category."
