[FEATURE] Adding fields for source, artist and track title to "downloads.db".

[seafloyd16]

Is the feature request related to a problem. Please describe it.

I cannot identify songs from ID when I try editing the database with a GUI database editor.
At least, it is helpful if there are fields of source, artist and track title.

I've modified the scripts myself.
But I am glad if it will be implemented at further updates.

Thank you for this great open-source project.
