When you are in settings, and click Background Audio Analysis, this text appears.
“Fast audio analysis requires substantial resources and may cause you PC’s fan to run. Do you want to turn it on now?”
I would suggest two changes. First, change “PC’s” to “computer’s” PCs normally refer to Windows-based devices. Therefore, you might want to keep more generic.
Second: When you say, “Do you want to turn it on now?” the “it” would normally refer to the last noun - the fan. No, I don’t want to turn the fan on now. 
You might want to say, “Do you want to turn the background audio analysis on now?”
Of course, this has nothing to do with music, but it does raise the bar a wee-bit on quality of information.
