I think tracker music being made with "passion unlike modern music" is a bit of a trope, honestly I think the unique sound is genuinely just down to how it's constructed. Rather than something like MIDI where only instrument and note data is saved ( and thus it's up to the midi device to decide what the instruments sound like), tracker files usually self contain the samples of the instruments inside it, allowing the instruments to be totally defined by the composer but it's still ultimately being made by the sound engine at runtime (allowing stuff like tempo changes or instruments being added / removed on the fly ). I think that's the real unique part of tracker music.
There's a game called Rez for the PS2 and I think PS4, this took advantage of trackers but cutting existing tracks into chunks that a tracker could use, and then adding beats, individual samples etc. On the fly in time with the music. Real cool, shame it hasn't had any form of sequel
