Demi Lovato wants to bring more ''emotion'' to music.

The 'Skyscraper' hitmaker - who underwent a three-month stint in rehab in 2010 to receive help for self harm, bipolar disorder and an eating disorder - has learned to ''connect'' with her audience by being truthful about herself and admires the work of Adele and Taylor Swift, who make catchy, honest songs.

She said: ''For a long time, I was pretending to be someone that I wasn't, and I was miserable. When I came out and said, 'I'm human, I've got problems, but I'm willing to share them', that's when I started to really connect. I've just begun working on my fourth album, and I want to do that in my music too. I'm tired of songs that don't have much emotion in them.

''I love the way that Adele has carved out a path for a singer that's very emotional, but I also love how Taylor Swift can do the same thing--she puts a lot into her songs yet they're still very catchy.''

Demi, 20, wants her music to stand the test of time as she is tired of ''trendy'' records.

She added in an interview with Teen Vogue magazine: ''I will say that I'm tired of all the dubstep that's on the radio right now - I think it's going to be out in two months. I want to make something that people will listen to for a while, rather than something that's just trendy. I feel like I've grown as a person, and I want my music to grow with me.''
