It is important to realize that downloading music may not always be legit. It depends upon which website you may be downloading music from as well as which type of music you are going for. For example, you can find virtually every type of music on YouTube in the form of videos however there is no way you could officially download YouTube videos.
All you can do on YouTube is save certain videos as well as like them and then come back to listen to music featured on it or watch a music video right on the YouTube platform itself.
That may not be what you would like to do as you may have your own device where you would like to save as many music files as you can. You will have to look for the right websites that feature downloadable music. Look for websites that have permission to feature and permit downloads of their featured music.
Avoid those who scrape the internet for music files and compile them to share with others to download. This is an illegal practice. You can find yourself in a problem and your device may not be safe as such websites can even feature dangerous files.
