For the past month (at least), a lot of songs will repeat 2-3 times even if the repeat one mode is not enabled. For some reason, it doesn't seem to happen with every artists. I always use the shuffle mode and I use the repeat mode as well (not the repeat one mode).
At first, I thought the it happened because the song appears on multiple albums but I confirmed that this is not the reason and I have a coworker that has the exact same issue.
