+#!/bin/bash
+# Prints media info from mpd, youtube, pandora
+
+# Priority:
+# 1. Prints the title of the mpd song playing, while scrolling (WORK IN PROGRESS)
+# 2. Prints the title of the first open YouTube window, while scrolling (sexy!)
+# NOTE: It works if the tab is in focus, so seperate the youtube tab from 
+# the rest of the browser so you don't have to keep it in focus and the script will work.
+# 3. Prints "Pandora Radio" if there is a browser window with pandora open (same principle as above)
+
+# Note: on tint2, set interval=0 and continuous output=2 or larger
+# (in general continuous output should be larger than sleep time)
+
+# TODO: start from the beginning if the output has changed (if the song has changed)
+
+# Another way
+# b=${a:12:5}
+# (where 12 is the offset (zero-based) and 5 is the length)
