On my channel you can listen to the complete Metroid soundtrack . I finally found some time to upload the missing pieces from the "Metroid Prime Trilogy". I gave my best to upload every track in high quality. I hope you enjoy the result as much as I do. ;)

Here's a brief overview of all the Metroid games. To all these games you'll find a playlist, including every song of the game's soundtrack:
