For me, "crate" is now associated with anything rust (and I'm neither a rust person or a programmer) - if I see crate in relation to tech, "it has something to do with rust."
I'm with you! It's possible that at one time I thought as you (also being a music fan), but in the past 5 (?) years you can't trip but to find someone talking about rust in the tech spaces. Not only context, but era (point in time?) as well.
I guess context matters! ;-)
