While YouTube Music isn’t missing out on a basic feature that you’d expect it had at launch, the feature is in extensive A / B testing and is only available to a minority of subscribers. Earlier today, one of the first changes was spotted: the ability to set a runway to repeat. Unfortunately, although it has been spotted in the wild, the functionality doesn’t … what is the term – works?

The change was spotted on the YouTube Music subreddit, and I can confirm it’s live on my device – for some definitions of ‘live’. The change lets you select the snooze button and cycle through the options while casting, but that doesn’t actually seem to affect anything. The person who spotted the feature claims that it disconnects entirely after playing once. My own tests were slightly better: the selection of a single song to repeat was simply ignored and the next song would be played. If I tried to repeat a playlist or an entire album, however, there was an error and the cast would crash with the following error:

Error: error.

The appearance of an interactive icon is almost certainly an indicator that change is in the works, but today’s news almost sums up the YouTube Music experience so far: if a feature isn’t totally absent, it is missing for a few people in an extremely slow or simply interrupted deployment.

One day, YouTube Music will be a full music subscription service and app – or at least, it will meet the benchmark set by Google Play Music – but that day is not today.
