1. First of all, you need a music player. This tutorial is based on Hypster Player, you can learn how to make one in THIS tutorial.
2. Go to Customize > Edit HTML. Copy THIS code and paste it BEFORE the </style> tag (use CTRL+F to find it).
3. Now you have to put THIS code AFTER the <body> tag (use CTRL+F to find it). Replace MUSIC PLAYER CODE with your Hypster Player code. Click Update Preview to see how it will look like and, if you like it, click Appearance and then Save. Well done!
P.S.: To move the tab more to the right, find left:50px and increase the number to your taste.
P.S.2: You can use other music players, but you will have to change some little things in the code. I suggest you not to use others players or change anything unless you know what you are doing. (credits)
