Asset Type controlled vocabulary term for audio recording with one track?

[Tim Lanza]

Hi. 

I'm still very new to the world of PBCore - and metadata schemas in general - so hope this isn't too naive of a question. The Asset Type Controlled Vocabulary seems somewhat limited and I was wondering what people use to describe an object that has only one piece of recorded content. In my specific case, it is a grooved disc that only has one track, which happens to be a song that is not part of a larger series of songs. Looking at the list of terms, it appears that Program might be the closest fit. Any insight would be appreciated.

Thanks,
