First off, who are you? What qualifies you to judge or dictate someone else's opinions? Is there anything that can actually lend you credibility? Besides what you preach... and your narcissism?
Credibility? I don't know, what are you looking for? I don't have a doctorate in music, sorry to disappoint. I do know a fair bit about music though.
Want me to list what instruments I've played? Want me to list all the different genres I have delved into and have a respectable knowledge of? This thread is already pure wankery so I guess I will indulge myself and list them for your amusement/pleasure/sorrow.
Played saxophone 3 years in middle school.
Played bass guitar 4 years in high school.
Played guitar for 8 years, never seriously, just at an amateur level.
Played keyboard off and on for 6 years. Not very good. Just for amusement mostly.
Played synthesizer for a year. I have an Alesis Ion, which has so many features it's ridiculous, but I'm learning slowly. I need to take piano lessons, and get a keyboard amp so I can stop using my guitar amp for it. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
Hmm, genres. This is a general idea of everything I listen to/have listened to/am acquainted with. Will start with the most obvious and move down.
Classic Rock - know the basics and a bit more. From Yes, Jeff Beck, the Dead, Zappa, blah blah etc etc, everyone knows classic rock.
Jazz - know 30s big band and some early sax stuff, not much modern cept Dave Clark and Bela Fleck
Blues - SRV is a God. Know a small amount about chicago blues and other blues, Guy, Allison, King, King, Waters, Collins.
Classical - not much. nothing more than your average joe schmoe, unfortunately. Wish I did.
Rap - very little compared to the rest of this forum and the rest of america, wont find me losing sleep over that though.
Grunge - Pumpkins ****in rule. PJ is/was badass, was favorite band for many years, was obsessed in high school (who wasnt). Screaming Trees are badass. AiC forever, used to be 2nd favorite band after PJ. SG is pretty good. Nirvana is ok. Some other grunge is good.
Now for the fun stuff:
Indie rock - know a lot. I'm not talking about the Killers, I'm talking about Bedhead, Sparklehorse, Slint, Mercury Rev, you name it, I know it.
Indie pop - same story. Stereolab = one of favorite bands. Flaming Lips, Low, Broadcast, Air, name it, know it.
Metal (more popular type) - melodic death I know a decent amount about. In flames, ATG, Dark tranq, amon amarth, haunted, swallow the sun, blah blah. Good stuff mostly.
Power metal - blind guardian, hammerfall, freedom call, gamma ray, children of bodom, etcccccccc
dance/techno/electronic - Yay. Daft Punk, Basement Jaxx, Royksopp, Orbital, Global Comm, Lindstrom, Massive attack (and other trip-hop), booka shade, etc etc blah blah
80s stuff - jesus and mary chain, joy division, talking heads, depeche mode, cocteau twins, sonic youth... dont like too much else from the 80s though
Now stuff most of you have probably never heard of, but isn't really that unheard of for "music people" or whatever:
post-rock - was my favorite genre for a couple years. I'm an expert. From the pre-beginnings (slint) to the real beginnings (tortoise, mid 90s) to the primetime (later 90s, mogwai (favorite band), labradford, godspeed) to more indie acceptable era (early 00s, sigur ros, eits, gybe becomes legendary) to recent (lot of trash, but 65dos, caspian, hammock, a few others, are good) I have like 200 post-rock CDs. This is my genre dawg.
IDM - another favorite genre. the 'pusher. AFX. u-****in-ziq. plaid. boC. kid 606. aaron funk. amon tobin, that silly latin dude. proem. apparat. outputmessage. luke vib b b bert. mouse on mars. AUTECHRE. love it all. You may be wondering wtf IDM means. Stands for "intelligent dance music". Don't blame me, I didnt invent the name.
other electronic stuff - dunno what to put here, mostly "ambient" electronic, but not really ambient. some DNB. a smattering of techno/trance (very little) ulrich schnauss, ISAN, sasha, bjork, arovane, seefeel, prodigy. whatever else electronic i listen to, which is a lot. a lot of electronic pop, too.
And finally, stuff most noone has ever heard of, and probably never will. And if you listened to it, you would probably think it either wasn't music, or was utter and complete shite, because your musical taste sucks (haha!):
Experimental ambient/noise - Yay. Love this genre to death. Including pure noise, neo-classical, early ambient, acoustic ambient, dark ambient (MUAHAHA) Merzbow. Fennesz. Oval. Pan Sonic. Helios. Eno. Belong. Hecker. Eluvium. Lustmord. Raison Detre. Coil. Experimental Audio Research. Flying Saucer Attack. Yume Bitsu. Amp. Fuxa. Fridge. SOTL. JJ. Manual. Jan Jelinek. List goes onnnnn and onnnnnn.
Black metal - You had to know this was coming. See thread "Black Metal" for more discussion. I don't know shit about this compared to the "TRVE BLACK METALLERS" that only listen to metal, but I know a good bit. Favorite bands: Weakling, Deathspell Omega, Xasthur, Emperor, Ulver, Taake, Satyricon, Judas Iscariot, Nae'blis, Marduk, Immmortal, the rest of the shit in that thread, and lots more.
Folk metal - Yay, this is also fun, though I don't know as much about this as black. Ensiferum. Moonsorrow. Thyrfing. Finntroll. Tyr. Summoning. Bal-sagoth. Enslaved. Windir. Good shit. Not as XTREME as black metal.
Yep. That's about all I listen to. With a smattering of other shit I probably forgot to mention, like the occasional pop, industrial, hard rock, etc.
