Faith No More was a band who I liked upon first hearing them in my senior year of high school, but after venturing deep into the thrash, death, and black metal niches in later years, I'd grow to hate FNM.
Now that isn't to say I hate Faith No More because they're not "true metal," it's that all the songs I've heard from them are cartoony, nasaly alternative metal with some "odd" musical quirks just to make themselves look "musically well-rounded." These guys dabble into many forms of music, and nearly all of their attempts come out sounding like cheap shit. It doesn't help that Mike Patton is an obnoxious, self-indulgent, self-aggrandizing hack with a lousy voice.
Seriously, if I want to listen to music with funk (I can't say I've listened to much "traditional" funk music), I'll check out the prime material from Living Colour and Herbie Hancock's 70's output. If I want to listen to avant garde metal, I'll listen to Sigh and Pan.Thy.Monium.
Faith No More isn't quite as abrasive as Iwrestledabearonce, but they're still really bad.
