His last few musical efforts haven't been too flash, but if you're referring to the Cobain/Love stuff, well there's two sides to that story, & I don't put much stock in one of them myself.
If not that though, why exactly? What has he done? I 'm no fanboy so wouldn't have a clue, the last I heard, he fell off stage, broke his leg, went & had it set, & came back and performed in a wheel chair rather than let down the paying fans, & I thought, yeah, cool.
I certainly wasn't thinking, gee, what a wancker.
