Thanks - enjoyable! Where it says to pause and play a favorite track I picked this one:
https://www.youtube.com/watch?v=j5AUm_xaE9A Try starting that and then click on Ditter's link and mute the sound on that video. It's much more mellow with Santana.
Editing to add that I should have said to open the Santana in a new tab and then you should be able to play both at once. I would have added my Santana suggestion to youtube, but I don't remember who I am on that site, much less a pw.
