Finished First Channel / Plex API Question

I created this channel, UTunes, as a bit of an experiment / get to know the Plex framework:
github.com/magas0/UTunes.bundle

It’s to use your own Plex music library information to search on YouTube for music videos (I miss the Vevo integration in the music library).

In the code I have been accessing the Plex libraries via the REST API. Is this the best way to get Plex information from within a channel? Or is there a better way?

You can see my code here:
