@hiccup, did you experience this with v2.5?
Certainly not on this scale. I only remember often having some very short clicks/pops when switching a song in the past.
On my current system this only happens when asio is selected. Other settings (buffer size, fade, etc.) don't seem to make any difference.
The 'snippet' is not a pop/click, but indeed some very brief sound garbage.
I just now installed a clean 2.5 to compare, and with the same settings it does not happen there.
b.t.w.:
It also happens when I play a song, then stop it, and after a few seconds start that same song again.
