You should download the application "Spotify", register (it's free), and then enter "Lost in the Stars" in the search box. I just did this (the search, I've been a Spotify user for quite a while). You can also just go to the website, sign up, and listen there.

Spotify is the best listening app ever, because you can enter the name just about any song, artist, composer, and listen to whatever you want. It is free (there are occasional ads, which you can get rid of by subscribing to the premium service, but you don't have to).

This is by far the easiest way there is to listen to the songs you want to hear. It will take you a couple minutes to download and register, and after that, you can listen to anything you want, for as long as you want. and it costs nothing.
