Katy Perry thinks the music industry is ''kind of brutal''.

The 'Dark Horse' hitmaker believes the industry is ''going through something very strange'' at the moment and has urged people to ''stay true to themselves'' through it all.

She said: ''If anyone else can tell, the music industry is going through something very strange, and I think young people are really in a struggle with online services and ideas of what they should be and what their life should be about. I felt that same way too, and I think a lot of us feel really alone even when we have over 75 million people following us and liking our stuff. This industry [is] kind of brutal. Just stay true to yourself. That's all I ever did. I didn't really have very much fear. I don't have any fear anymore. I really don't care what the outside world says about me 'cause I know who I am.''

And the 33-year-old singer feels happiest when she's ''connecting with God and nature''.

Speaking at Citi Sound Vault at The Theatre at Ace Hotel, she added: ''I believe in a higher power bigger than myself, and I believe in God. I don't know if it's the same God you believe in, but She is incredible. People that think you're happy when you have money have never had money. It's not about getting things.

''It's about connecting with God, it's about connecting with nature. This year, I saw the God in all of us - in each and every single individual. Every single individual is absolutely enough and worthy and can do whatever they put their mind to.''
