Spanish singing rock bands

There’s many good famous Argentinian rock bands from the 80s and 90s with clean vocals. Soda Stereo, Divididos, and Attaque 77 (sometimes spelled A77aque) would be my recommendation to start with for bands that lean more towards the hard side of Rock (there’s more, but some I won’t recommend because of their members’ later questionable actions, and the rest you’ll find by following the trail of related artists from the above set). For Pop/Rock start with Los Rodriguez, Charly Garcia, and Los Autenticos Decadentes.

From other countries off the top of my head I’d recommend Mano Negra, Cafe Tacvba, and Molotov (warning: explicit lyrics).

I thought it was a reference to the Westworld character…

Sounds like what you want is tracing. OpenTelemetry is the de facto standard for that. Couple it with aggressive sampling (here’s a great talk on it https://www.usenix.org/conference/srecon24americas/presentation/cruz ) and you’ll have a very efficient way of identifying use patterns.
