I saw a few arguments here trying to link between musical preference and sound appreciation, which I find odd. I personally (probably largely thanks to my father), have a relatively diverse taste, albeit with a distinct preference for down-tempo electronica of various sorts. Which brings me to my point. I listen to vast amounts of electonica because I like the sound (synths etc). That being said, there are a great many tracks in the genre which are musically dull (at least to my ears). So there is always a balancing act.
But saying one genre is more or less hifi than another (there was somebody who said trip-hop was lofi, I don't know what you are listening to), seems silly. Because even in the so-called "overproduced" sound there is a certain aesthetic which some people might find pleasing (the use of distortion was considered by many to "ruin sound"). Better gear helps you get better resolution of these things just as much as the sibilance in a singers S's, or the pluck of the pick on an acoustic guitar.
I don't think one can truly enjoy music on an iPhone speaker, because what you can hear is often lost in a sea of other noises pretty easily, and distortion-heavy genres (metal, thrash-core and the likes) sort of drown themselves out, sometimes hi-hats go entirely unheard. But iPhone speakers are, IMO, the extreme lo-end of the spectrum. Laptop speakers, I find fatiguing,but to get an idea of the music, they're fine.
As to older recordings, my favourite example of this is a vinyl I have of Louis Armstrong, that dates back to the 40's. From a hifi point of view, it's appalling. It sounds like there was a room where the musicians were playing loudly, and a condenser mic at the end of the ventialtion tube. But there is such an ambience of FUN to it. It sounds like they're ENJOYING themselves, and that (emotion) is something that should be apparent regardless of hifi, a good reproduction of sound just enhances that, and IMO, adds a fair bit of magic to music (I would LOVE to hear that same performance having been skilfully recorded and produced with technology available today).
So in summation, I think that people who love music are more likely to become audio enthusiasts, which increases the percentage of music lovers among the audiophile population. But it is still bold to equate one to the other. And, as with any other consumer goods, audio gear also attracts some knobs who want to show off how clever they are, and how much better their soundsystem is.
