A lot of translations have it refer to anger, but the original Hebrew word seems to refer to our spirit/strength. Some also add that the spirit should be "held back until afterward". I could be wrong, but I get the sense this verse is more about how it is unwise to let out your feelings and act on them impulsively without considering the consequences, rather than, say, honestly talking to a close friend about some rough emotional turmoil you've got going on. In other words, don't let yourself be ruled by your emotions, especially in a way that will harm other people. Sometimes they do need to be bottled up/held back so as to not act on impulse. It's healthy to talk about them at the right time, but don't let them direct all your actions. But again, I could be wrong. Correct me if I am.
Beautiful Eulogy is thankfully pretty understandable, which is probably on purpose so that anyone is able to understand the messages they're conveying. They have a really good sound too that's pretty contrary to most rap music these days. I'm also not really much for rap, but I have exceptions, and this is one of them!
I'm a big fan of the hymns, but for more modern contemporary Christian music, I either go for rap group Beautiful Eulogy or some of Montell Fish's early albums, particularly It's Beautiful. Some of my favorite tracks from Beautiful Eulogy are Beautiful Eulogy (same name haha), Instruments of Mercy, Symbols and Signs, The Size of Grace, Mosaic, and Messiah. For King & Country is a good group too.
In terms of specific songs, MercyMe's I Can Only Imagine is wonderful. Shine by Sisterbrother is nice and calming. Besides all these examples, I often go to a playlist of either Christian lofi or more chill worship music for devotional time. So yeah.
