I agree completely. On a mainstream level, she is incomparable... Peaches said she liked the idea that Lady Gaga existed, to introduce the kids to grittier stuff like her, in some interview in my local newspaper... She said that Lady Gaga is making this weirdness cool and palatable to the masses...
And she can actually sing and write her own songs; which is OK... Although her songwriting and music are not really the point...
