In the tracklist editor, if I enter "X.XX" as track time instead of "X:XX", it doesn't accept it. From the pages where music can be found, at least Soundcloud uses this format for tracks, so it would be useful to have it parse it to "X:XX". The most confusing thing is that at first it seems to work: "X.XX" appears on the track time area in the preview, but doesn't stay there.
