More detailed data store records for each song

[martinatime]

Dependency on Song Discovery and Cataloging (issue #6)

Develop the ability (or use a library) to retrieve all of the meta data associated with each song file and store that data in the data store record associated to the song. This should include

• ID3 tags
• iTunes specific tags
• (optionally album artwork)
• Any other tagging

Possible enhancements to this

• Hashing with SHA1 and/or MD5
• Fingerprinting for use with MusicBrainz or some other Music ID databases
• Fuzzy parsing of the filename to hint at more information

Does DRM on media files restrict access to the metadata, or just the ability to play the file? If it's the former, will we still index DRM'ed media files and at least retain the basic information that can be extracted from them without having to deal with the DRM itself?

The hashing is a really good idea. That will come in handy when we get to the point of identifying duplicates within the library.

I'm not sure what is meant by Fuzzy parsing of the filename to hint at more information. Can you elaborate?

One other thought. We should allow the user to manually tag records. The tagging could be implemented along with issue #13, but we probably need to make sure to allocate space for that information at this point.

• Good point on the DRM. I believe that the meta data is exposed as I believe that the information pertaining to the DRM is in that meta data. We'll have to see how this works and take it case by case as each DRM implementation may be different.
• Thanks. I had thought of the hashing when I attempted something like this using a script. It takes a lot of time to has a ton of files. We'll have to see if we can mitigate that time with multithreading.
• The fuzzy parsing of the filename/path - I guess the best way to explain this is that you could possibly use the segments of the folder path and the parts of the filename to fill in or suggest parts of the meta data. The example I have is a file that has no real meta data inside of the file but was in a folder path that was /artist name/album name/song name.mp3. Also I have seen mp3 filenames that are something like artist_album_song.mp3. There's no consistency.
• As far as manually tagged records, do you mean give the user the ability to add new tags? Or do you mean updating existing data? Both are fine by me I'm just asking for clarification.
