Audio file can't play

I used sound.sound to play audio file ,but it report a error as follows:
RuntimeError: Error opening 'Live.mp3': File contains data in an unknown format.
I don’t know if it’s the problem of audio file.
I feel very depressed.
Thank you so much in advance!

Try saving your file in a different format (e.g. .wav):

Audacity is often a good option for this sort of thing:

Hello Michael,
Thank you for your kind help.
I have tried to use .wav as you suggested and I successed!
Thank you!
