Musicians,what is important metadata to include in your audio files on Soundcloud and similar? What about if its under creative commons ?

Metadata - artist, album, producer, composer, copyright info, etc.

SGT (Join to see) - I appreciate it. I guess it depends on if it's original content or not. If I wrote and recorded it, I would just say it was done by me. If it's another artist however, be sure to give everyone involved their due credit.

SPC (Join to see) - The question is regarding a musician and her/his original content. Applicable info would be:
link to artist website
ISRC code
URL to copyright or Creative Commons info
all people involved with the works
