In Diamond Dust Act 2, Tails bonus stage failed to load properly. Sorry for the terrible audio quality, going to re-try it.
Edit: May be related to the fact that now Knuckles sends me in Tails bonus stages.
Edit2: It seems like Knuckles started sending me to Tails stages since I jumped between the two of them in Spring Stadium Act 2. (just a guess though, not my screenshot)
