We Call It Acid by Organ Donors and A*S*Y*S

This slightly truncated version of the song is the best I can find on youtube, although you can hear the whole thing on spotify. (https://open.spotify.com/album/2PssKYtcCHrzs4xI5yM7pb)

This is another song that reinforces my central premise; to me, a year ago, this was a fairly typical acid techno song, of the type that I was familiar with from the rest of A*S*Y*S's output.  Of course, I was wrong about that, A*SY*S doesn't do acid techno so much as they do acid trance and hard trance.  Discogs calls this song electro house, and the youtube description calls it subground.

EDM is over-split and over-categorized.  Nobody really cares all that much about the finer distinctions between the styles.  And they're too finely defined if the same song gets categorized differently in different venues, or—as happens in the youtube comments section of a lot of these—people argue endlessly about what exactly it it.  Personally, I find that I like the trance structure with build-ups and drops, quite a lot, and I like the really hard sounds of hardtrance and some of the hardstyle when it isn't caricaturish and noise.  I'd probably find plenty to like in hardcore or gabber if I got into it, although given how much hardtrance and before that hardstyle blew up my collection, I'm reluctant to explore it much. (And my limited exposure so far hasn't been all that promising.)

I might even like a lot of British hard house.

But I don't worry too much about genre labels.  If some hard house makes it's way in, I hardly even notice, much less complain.  If some regular trance with boosted bass makes its way in and doesn't sound out of place, I don't care.  My DJ set mixes are mostly hard trance and acid trance, but feature a fair number of early hardstyle songs, acid techno songs, and even a few classic trance songs and subground songs here and there.

In fact, although I keep saying that I'm not really in collection mode right now, I do still keep finding more stuff.  I recently got a bunch more DuMonde tracks (which is funny; they were on my radar from the very beginning, but I put them on the back burner until just now) and I've filled up a few corners with Max Savietto (and his various aliases) stuff, including some new "Loop Hole" remixes from 2012 and a whole new collaboration that I'd missed, Evergray.  I earlier got a fair number of tracks from Resonate: The Brutal Sound of Hard Trance which was a British collection.  There's seven such collections, and I only did a cursory scan of the first one.  This collection says hard trance, but according to most, it straddles a line between hard trance and hard house a lot of the time.
