Spotify "preview" audio problem in Match window.

[djay pro mac demo] When previewing a track (in the Match window of the Spotify integration), the first time I try it the preview pop-up loads and plays just fine. But then, if I soon after click to preview a different song on the list of Match suggestions, the preview pop-up window will appear - with the artist, track name and artwork listing as I expect - but the play button and transport controls in the pop-up play the audio of the FIRST song I previewed. This continues to happen as I try to preview other songs, and rights itself after the Match window refreshes (which it seems is something I can’t control and just happens whenever it likes). I preview a song. Listen for a minute. Move on to preview other songs, but only here that audio of that first song I previewed for all the previews after that. Strange behavior.
