I use a really cool website https://coconvert.com/youtube-wav-converter.html where I convert YouTube to wav .I can listen to music for free and of the highest quality, which is amazing in my opinion. It is not only for music; I can download any YouTube video and have it on my device available in offline. It really saved me when I went on a 10-hour trip to Arizona without any internet. I remember when I was struggling with this issue so I would love to recommend this website to everyone who is not willing to spend money on quality music and videos.
