So he traded his soul to Azavarn for his own theme music?

Err, no? I'm not sure sprites have much of a soul to begin with. 
Azavarn would be provided his theme music for free, since it's his job to play music. 

The sprite would also be a spy since he can listen in on people and record stuff. As a bright, cheery, innocent ball of light, every hero would want him around!
