I can confirm with latest 2.1.0-alpha-pre on OSX 10.11.6, that the file mp3 (BEFORE.mp3) is not displayed correctly, and end is cut @ 2:40.11. The file works correctly in other players, e.g. Quicktime player, iTunes.
See the detailed file comparison between the non-working (BEFORE.mp3) and working (AFTER.mp3) versions, may give some hints. There are some errors in the non-working file, that Mixxx might choke on.
