For example, when i shuffle all of my songs (all of them in same directory on my PC) with the "play more> play all track shuffled" option at right click to bottom tab (song control tab), the first song starts with tempo control's sample rate changer applied to it, no problem here. But! when first song ends and it's automatically switches to another randomly shuffled song, the second song plays at normal tempo (tempo contoller's sample rate changer not applied to second song).
