can we flip tracks or must one end?

if im listening to say ocean surf and i get tired of it can i switch to the stream one 15 mins later or do i have to wait for a track to end before going on to a new one? im sure there's subs at the end of a track that im missing if i switch earlier, but dont know if thats a big deal. for example right now im listening to the stream one but now i need silence. so wondering if switching to the ultrasonic is OK.

The way the program is designed, you *can* switch in the middle, but I wouldn't do it too often.
