TrackState

Which records to show, by what the station has of them rather than by what they are.

cached the audio is on this machine, so it can be committed to the running order now uncached it is not, which for most of a library is ordinary rather than wrong unmeasured no trustworthy measurement, so no cue points and no level decided before air benched every copy written off, which is the one state that means it CANNOT air failing a fetch has failed and is backing off. Not benched yet, and often the state before it

type TrackState = 'cached' | 'uncached' | 'unmeasured' | 'benched' | 'failing';
