birth-1997 or so: didn't care much about music, but gained a taste for techno stuff since it was popular in Spain at the time
1997-2001: still not enthralled with it, but a taste for it awakened; first musical memory is the soundtrack from Mechwarrior 2 and its Ghost Bear's Legacy expansion pack, which have stuck in my memory to this day, even without having heard them for years; after that, moved to Africa, didn't have much to choose from so I listened to songs by the Beatles and Blood, Sweat & Tears with high frequency; later acquired a few CDs of my own, but they were mostly shit(enjoyment of Creed is an eternal point of shame in my life)
2001: moved back to the USA, got online, found Dead Can Dance by a random and fortunate fluke; got back into techno shit as well, but Dead Can Dance is what made me understand how powerful music can be, and remains my most highly-regarded modern musical effort
2002-2005: begin to appreciate classical, usually turn the car radio off if I can't find it playing on some station; hear ambient music for the first time via a late-night program broadcast from the university station in El Paso, fall in love with (some of) it; start renting music from the local library branch; discover a few more things that ignite some level of interest(Leonard Cohen, Nick Cave, ethnic musics); also take a "world music" class in college, through which I gain appreciation for Indian classical, while simultaneously coming to understand how easily the liberal collegiate mindset will embrace anything that even appears to be non-Western, as the class tried to hold modern Latin American/Caribbean genres like samba, bossa nova, and calypso in the same category as African tribal music and Imperial Japanese court music
2005-2007: a friend instills an ironic love for terrible glam bands; the fact these were called metal, even though far from being such, happily points my curiosity towards heavier things; start delving into Iron Maiden as well as more bad things such as "NWOAHM" and Gothenburg bands; at this stage I find any metal without solos to be too repetitive and droning, likely a holdover from when I got into glam bands, many of whom did actually have good guitar solos
2007-2009: hear about black metal, wonder just what the fuck it is, start looking into it; first interests contain a lot of crap as well, circus metal like Arcturus, while my natural predilection towards appearing unique drives my to avoid things that get too much praise, such as Ulver; also can't stand most death metal, but black metal(even of the more genuine variety) has heavily clicked; discover ANUS through an innocuous mention on the Wikipedia page for Vikingligr Veldi; develop an elitist mindset, but get somewhat carried away with it as well; become obsessed with knowing about as many genres as I can, minus a few obvious crapholes like emo and post-hardcore
2009-2010: realize how pointless it is to try to stay on top of multiple genres, as I have no desire to make a career as a reviewer; truly "get" death metal for the first time; also delve heavily into classical for the first time, but after a short while I realize I don't want to spend what will be easily over a year of my life simply coming to understand something to which I will never contribute, and satisfy myself with simply loving it instead; at the same time I realize that metal speaks much more clearly to me, and begin the process of understanding why; with almost the entirety of my musical explorations now focused on a very narrow swath of two specific genres(death metal and, more so, black metal), this process accelerates rapidly; tone down elitism (or false elitism) in the sense of knowing that my efforts would be better spent in increasing the good rather than decreasing the bad, as the good will not increase on its own, whereas shit will always decay into nothingness
late 2010-2011: get tired of having a section of powerful music stick in my head as I'm falling asleep, and clearly hearing in my head what developments I could make off of it(e.g. the solo that bursts forth from among the plodding density of riffs in Bathory's "Home of Once Brave"), and soon after that, get tired of having various musical ideas of my own without any means of expressing them or even keeping a record of them; begin the process of learning to play music; expect an album in about five years
