The rhythmic cells exercise 4 Fast mp3 does not end after the exercise. The exercise lasts 33.06 seconds, while the mp3 continues with some other recording until it ends at the 1:07.47 time frame. The mp3 only needs to be edited to remove the part that does not belong. The slow mp3 is ok but i never use the slow one since i listen to these using Transcribe which allows me to choose the speed i need (similar to vlc ).
Not a big concern. just thought i would report it if you want to fix it.
Happy holidays
