I'm a fan of RadioParadise, coded JSON API for it on top of Phalcon.
API Info: http://zvoid.net/api
JSON API: http://api.zvoid.net/rp
API Demo: http://app.zvoid.net/rp
Website hosted by DigitalOcean vps should be up 24/7.
You're welcome to use this API to create your own app.
I have plans to extend it more in time.
This is one of my first Phalcon apps :-)
