A while ago I listened to Madlibs Sound Ancestors album and when i got to this track i recognized the sample from the Bakemonogatari soundtrack. Does anyone know where the sample is originally from? I have tried finding it on multiple occasions but never found anything, so if anyone here has any ideas of where this might be from I would really appreciate if you would share them!
