Script that reads currently playing song from MPD via MPC and queries Tinysong for a sharing URL, then spits out a nicely formated text for you to tweet.

tinysong.rb

# coding: utf-8
require 'net/http'
require 'json'
require 'cgi'
require 'extlib'

playing = `mpc current`.chomp
key = "insert your API key here"
url = "http://tinysong.com/b/#{CGI.escape(playing)}?format=json&key=#{key}"

resp = Net::HTTP.get_response(URI.parse(url))
tiny = JSON.parse(resp.body)

unless tiny.blank?
  puts "First match: #{tiny['ArtistName']} ♪ #{tiny['SongName']}"
  puts "#nowplaying \[#{playing}\] #{tiny["Url"]}"
else
  puts "Found nothing. Quit listening to weird shit."
end
