This idea has been set to Not Right Now for quite a while now. We thank you for all the votes and support. We've discussed it internally once more, as we’re currently looking into different ways we can enhance user experience when transitioning between songs, including on different devices.
As there are no immediate plans to implement this, we’ll be setting the status to closed for now, to match our new Idea Exchange statuses.
This doesn't mean we won't revisit this idea in the future - we actually think it's pretty great, but want to set the right expectations as this isn't something that we can focus on in the immediate future.
If we do have any new information to share, rest assured we'll check back in here with a new status.
