The former Hole star is understood to be working on new solo material, as well as overseeing the upcoming Kurt Cobain biopic.
In a new online posting, she proclaims herself a "bionic" worker, while insisting the Queen of Pop is "weak" and "calculating."
"Madonna is a great businesswoman but come on, she's weak as an artist and we all know it. I like Madge but as a relevant musician it's a joke," Courtney said.
"She's singing from such a calculating, thought-out place all the time. It's never from her gut or heart of intuition, so maybe it sounds great and slick and you can hum it.
"Hard work and major discipline doesn't equal great art and all of those are great things - I covet them. I have great discipline and I do work like a bionic thing," Love concluded.
