Lorde has responded to Iggy Azalea's critical comments about her Kurt Cobain tribute at the Rock & Roll Hall of Fame induction concert in April but refuses to spark a war of words with the rapper.

The Kiwi singer took to the stage with remaining Nirvana members Dave Grohl and Krist Novoselic as part of a tribute to Cobain and his music.

Azalea enjoyed Lorde's performance but did not find it "appropriate", saying she thought the singer-songwriter's former bandmates should have chosen Cobain's peers to front them at the tribute ceremony.

"No matter if she killed the performance or not, I just don't think it's appropriate," Azalea told Billboard magazine.

Lorde responded in an Eastern States newspaper: "I've been in a position where I've said something in an interview where I've thought 'Damn, I wish I could take that back'.

"I don't know how (Iggy) is feeling about it. But anyone who's doing well deserves respect and I respect what she's doing."
