Possibly a bug with the music

[Plaid]

Just today I've been noticing that, during gameplay, when a song ends and another one starts, well, the previous song isn't ending, so I have two songs playing at once.

I've tried letting one of the tracks play all the way through to see if it would reset itself but it doesn't.

Obviously this is a sonic mess so I have to pause the game and turn the music down all the way down.

Has this ever been reported before? I have not installed any new sound drivers or anything like that. The only thing that could have coincided with this problem is today's Steam beta update.
Again, this is the first time I've noticed it and there's no way I would have missed it in the past; it's very apparent.

I've heard of this bug before but have so far never been able to repeat it and have never managed to get good repro steps from anybody who has experienced it. If you can find that you are able to get it to happen reliably with a specific sequence of events then post them here and I'll look into it.

I've had it happen several times. Not sure which mode, but it's either rush or survival since that's what I play mostly. It only happens after playing a while too. Seems to be more likely occur the longer I play.
