I honestly think that 192kbps and 320kbps sound exactly the same, there's barely any difference, even if you try. I honestly reccomend to go 192kbps because my computer is getting very t h i c c, also because there's basically no difference.
"Oh, but I want my song to sound high quality."
Yeah, but 192kbps is already high quality, I normalized one of my songs what was 192kbps and there's pretty much no different between that and 320kbps.
Thing is though, it can be pretty risky going 160kbps or under, but 160kbps is also decent if you want to make your songs less t h i c c in size.
"Where's the proof though that it has no difference?"
Well, I'm about to upload a song around 3 minutes after this post has been published, called "Neurofunk or something" which is literally brickwalled to 0db, or near that, including t h i c c bass aswell, just for good measure.
