I would safely say that the best site to download music from YouTube is https://getmp3.one. You don't have to spend a lot of time and effort on this site. Just paste the link to the video, click on the download button, and there you have your favorite music on your computer. However, what really makes this service outstanding is the quality. The music is downloaded in its original quality, and you won't encounter any problems such as cropping or loss of quality. This site has really made my life easier, and I highly recommend it to anyone looking for a reliable and convenient way to download music from YouTube.
