"First, finding the lyrics of the song that’s playing, and picking out the key words or themes from it"

I listen to Melodic Death Metal. Some of the themes in this genre are not suited to provide pictures one might want to look at. A blacklist or filter for some keywords could help here.

Would be nice if you could provide more examples for other genres.

It was a random sampling of songs that I was already playing while I was writing that. All my music is either folk (with a lot of Irish and American folk), rock, or indie. If you like though, you could try it yourself.

The great (or perhaps, not, depending on what you want) thing about the Flickr search is that it picks from a set of curated photos, so it's highly unlikely you'll get an unpleasant one. However since it is picking random pictures from the internet, don't run it where you'd get into trouble if something inappropriate does manage to come up.

I'll file that under "user error" :)
