Need help with rar file password

Hi guys
I have winrar installed on my pc and have used this program successfulle to open .rar files in the past.
My problem now is; I have downloaded a torrent of 108 mb in a rar format (again) , but this time it needs a password to open the mp3 files to be used. Can anybody adise on how to crack or do something with this tfle without a password.
There was no password attached to the file when downloaded.
Looking forward to some clever advise
Regards

Sorry, but discussions about illegal downloads and password cracking are not allowed on this forums. :cop:

Please take some time reading our rules.
