Paramore have been discussing the new material they are working on.

Speaking to MTV News, singer Hayley Williams said the material would be heavier than their last two albums.

She said: "I'm a big fan of a lot of heavier music. I've been listening to stuff like H20 and Set Your Goals' new album 'Mutiny!' So there's a lot of that. ... We all listen to so much stuff."

Williams said she was influenced by guitarist Josh Farro's writing process.

She added: "Josh writes most of the music, so he has got tons of ideas coming on like crazy right now, and it's really inspiring and motivating me.

"So, I started writing to some of the ideas while we were on tour, and hopefully with some time off, I'll be able to focus and spend a lot of time on that. We're hoping to have a good 20 songs done by the time we get off the road, and we'll see where we go from there by the end of the year."

The singer also said how much was riding on the new album.

She admitted: "This one has got to be better than (the last album) 'Riot!' and we all know that this next (album) is gonna be important to us. And we would love to record at home. We hope to work in Nashville, because we've been on the road for so long, and to be away from home has been tough."
