What type of music do they listen to, who are their favourite band(s), comments on their taste, what impact have they had on your own taste of music, etc.
I guess "listened to the most music" could mean either owning and enjoying the largest amount of music, OR spending the most time listening to music, regardless of whether they just endlessly spin Peter Andre and Eiffel 65.
The person I know from more than a passing meeting who listens to the most music is either:
- a friend of mine called Sinead from Ireland (surprise!), listens to tons of rock music - a lot of the scuzzier variety, doesn't shy away from mainstream rock or classic rock, but sways towards early indie/noise groups and punk/punk-inspired stuff - and drum and bass. Favourite band is The Smiths (or was when I last saw her). Still makes mix tapes, as in with actual cassettes, which I think is about the coolest thing ever. At the time I met her, I avoided most three-to-four-minute-songs verse-chorus-verse guitar-drums-bass-vocals rock bands, because I found most everything like that quite dull, but a bit of time around Sinead showed me I needed to pay more attention to subtleties in many of these bands formulas, that bands can still do very interesting things within that model.
- OR a lecturer of mine called Barry, taught German. Classical "snob". Favourite artist was Mozart. Mozart still isn't a favourite composer of mine, but I like his music a lot more now after Barry's descriptions of what was great about his music. Barry also gave me general recommendations on classical. He seemed more a fan of the classical and baroque phases than of Romantic and modern classical, though he had listened to, performed and could talk about all of it. He was more or less closed off to any other form of music, though he admitted being able to respect jazz.
I also once briefly met two flatmates of a tutor of mine who were very into music. Both seemed to download absolutely everything in the vague region of rock and popular music (though nothing too experimental or too charts-ey/poppy). One was a devotee of the Counting Crows, and quickly showed the pathetic pet tendency of CC fanboys to hate on the Dave Matthews Band. Even though I met them only briefly, they were quite a big influence on my listening habits. They initially seemed very "well-read", but for all their apparent devotion to hearing as much music as possible, they actually had a boringly narrow window of interest. When I started to bring up jazz, classical, reggae, metal, etc, they were completely unable to comment. I also thought later they came across as having listened to most of the stuff they talked about only very briefly and having impressions of it which were extremely superficial, possibly even listening to a lot of it just to be able to say they'd heard and judged it. Meeting them really emphasised the importance of focussing my listening on the most acclaimed artists within a genre, or those interest me the most (or who I think will do so), rather than pointlessly trying to listen to tons of music as quickly as possible.
