Okay someone messaged me about how to get one to work but I accidently messed it up :S Basically go to this link http://billymusicplayer.tumblr.com/ and follow the steps and you’ll get a generated code at the end. Copy this code then go to tumblr and customize your theme. Click customize HTML and scroll down to near the bottom and look for <body>. Click one line above that then paste in the code then press enter. Update appearence and save it all and then your done. when you close customization you’ll see the music player in the top right of your screen and it’ll say buffering for the first time. Just close the blog and re-open it and music will play :) Enjoy!
