How to represent track ordering with MusicRecording?

Trying to represent a music album/playlist, I wonder how to represent 
the sequencing of songs. Would it make sense to add a property 
trackIndex (Number, starting with 1) to http://schema.org/MusicRecording 
? It sounds a bit ugly because tracks could not be reused for multiple 
playlists, but how else is ordering being captured?

Thanks
