This is almost harder than the desert island discs thread the other month.
Black Sabbath. No ifs, ands or buts for this one. 50 years since the first album and people are still wishing they sound like it when they make stuff.
Tom Waits. Dude is a legend for a reason.
Judge Dread, though I would sub this for any kind of piss take punk (so Toy Dolls) and possibly some punk in general (I do like some GG Allin and Dead Kennedys). Though do I go as far as to include Frank Zappa in that? Not least of all because quiz me on Frank Zappa like those on the rest of the list and I will fail hard. Hopefully I can also include some psychobilly in with that one but that is close enough to punk that I am OK if not.
Korpiklaani. I see them pretty much every year I can so I kind of have to include it.
Dr Feelgood. Not a throwaway fifth answer but almost feels like it, even if they are on almost any playlist of mine.
Except that does not really cover things. Going through my music folder then I have various bits of classical and neoclassical, and the last CD I bought was a Therion CD (they are a metal band that often plays with an orchestra). Last songs added to music collection include some hard bass just because I found it amusing, and I have plenty of piss take remixes for the same reason
Biggie Smalls featuring Thomas the Tank engine is something I actually listen to. Give or take some of
Judge Dread I have not even included reggae. At the same time I have not covered my general dislike of ballads. Any of those do a ballad (and many of those have) and I am not interested.
Basically I think I like technical proficiency in music/instruments (that I did not previously make a nod towards Tom Morello, guitarist in Rage Against the Machine, troubling me here), in lyrics (and taking the piss is one of the highest forms of this as far as I am concerned, though stories/settings from Tom Waits is probably as good as it gets), and usually find it in older rock and folk metal, with the occasional bit of punk thrown in. There are also some outright classics that
percolate around in my
brain as well, though they might fall under piss take.
I suppose with all that then you probably would not be surprised by anything in my music collection, other than absences (if I only ever hear Deep Purple on a radio again I won't care, and they are far from the only "legends" with that status).
