It is a song pack contain some files being encrypted.
They can be decrypted by this script http://www.mediafire.com/download/3ttlbq475wld332/decjbt.txt. But need to connect iOS device. Decrypting process is also a bit troublesome. Are there any other method to decrypt jbt files?

Here are some decrypted files from other jbt.
