Line-length exception....

[philsmd]

Exactly. As undeath already pointed out there is a problem with the format or encoding of your hash file, it could be one of these:
1. wrong path to the actual "hash" (you point to the original wallet file instead of the extracted hash?)
2. you extracted the "hash" with powershell or manually set the default character encoding of your shell to something different than ascii/utf8 (maybe utf16 is used)
3. for some reason extra BOM characters were added to the file
etc

It's very clear from your output above:

Code:

Hashfile '.\hashes\music.txt' on line 1 ( ■$): Line-length exception
Hashfile '.\hashes\music.txt' on line 2 (): Line-length exception
Hashfile '.\hashes\music.txt' on line 3 (): Line-length exception
Hashfile '.\hashes\music.txt' on line 4 (): Line-length exception

that hashcat discovered 4 lines within the file .\hashes\music.txt . This shouldn't be the case with a correctly formatted "hash" file extracted by ethereum2john.py by using python 2.7 on the cmd (not powershell with special character encoding).

I would suggest that you open the file .\hashes\music.txt in a text editor.
Copy-paste everything starting from the $ethereum$ signature to the end of the line.
Insert it into a new file and make sure that you safe it with ASCII character encoding.
