Does anyone know a reliable way to download music from YouTube?

I’ve been really into discovering new music on YouTube lately, but I’ve been struggling to find a good way to download the tracks I love. It’s always tricky to find a reliable service that doesn’t complicate things. Does anyone know of a trustworthy way to get those songs offline? I really don’t want to miss out on my favorites, and it’s frustrating not having them on hand when I want to listen. Any recommendations would be awesome!
