Alanis Morissette has vowed to write songs until she's ''dead''.

The 38-year-old singer - who recently released her eighth studio album 'Havoc and Bright Lights' - admits she gets ''really depressed'' when she is not penning a new track and doesn't ever plan to hang up her microphone and give up her beloved career.

She said: ''I'll be writing records until I'm dead, whether people like it or not! I can't not write, if I don't then I get really depressed. I'll keep going, I promise!''

The 'Ironic' hitmaker - who released four albums in the 90s, including 1995's 'Jagged Little Pill' - insists she is ''excited'' that there is a bigger presence of successful female artists in the music industry nowadays compared to when she shot to fame in the early stages of the decade.

She explained: ''I'm excited about there being more of a sisterhood these days. Back in the '90s there was a lot of hate - the women I looked up to as artists were dissing me! It's not so patriarchal these days - there's more love and a lot less hate!''

Alanis admits the inspiration for 'Havoc and Bright Lights' - her first album for four years - was taken from a number of her previous records as well as her early musical influences in life such as Etta James and Leonard Cohen.

She added to Digital Spy: ''This record definitely feels like an integration of parts of my previous records. As a kid I was listening to Aretha Franklin, Etta James and hip-hop as well as music my parents were listening to like Joni Mitchell and Leonard Cohen. Obviously I live for big pop choruses as well, so the whole thing feels like a bit of an arrival point.''
