squeeze-alexa is an Amazon Alexa Skill integrating with the Logitech Media Server ("squeezebox"). See the original announcement blog post, and the follow-up with videos.
This is still in beta, so feedback and help with documenting welcome - please just raise an issue first.
Have a look at this 2-min video 
for a live demo of some of the new features.
- Intuitive voice control over common music scenarios
- Low latency (given that it's a cloud service), i.e. fast at reacting to your commands.
- Decent security (hopefully)
- Extensive support for choosing songs by (multiple) genres, and now playlists (BETA)
- Helpful, conversational responses / interaction.
- Full coverage of all LMS features, plugins or use cases - but it aims to be good at what it does.
- A public / multi-user skill. This means you will need Alexa and AWS developer accounts.
- A native LMS (Squeezeserver) plugin. So whilst this would be cool, at least there's no need to touch your LMS.
- Easy to set up 😱
