Why not just buy a used Squeezebox Radio for the kitchen and be able to treat it as a regular player in all respects, including perfect syncing?

An angle you might not have considered with having to pay for a subscription for an Alexa skill is that the cloud hosting has to be paid for somehow. Logitech may be paying to keep the MySqueezebox.com servers running but they're not footing the bill for my skills hosting. Sure there are free tiers on AWS but e.g. provisioning realistic database capacity for a whole community of users falls outside that. Just saying...
