Mediaplayer with curl -X GET

Hi! I’m new to HomeAssistant and I absolutely LOVE IT! :slight_smile: I’m an oldschool Winamp-user and I am currently controlling my winamp remotely using a http-plugin, for instance I can change to next track if I browse http://domain.com:85/next. So far I have only made switches using command_line to let curl get those url’s. Would it be possible to use the universal mediaplayer (or some other player gui) to remap each button to individual url-commands? If I could do that I could finally get rid of my old webpage and get that mediaplayer on HA to control my music at home.
If possible then how could this be done in the easiest way?

Best regards!
Matthew
