ID3 tags on playlist instead of filenames, without extended M3U

[GigaBrick]

I would like my playlist to show tag info instead of filenames.  I've found the EM3U solution here... http://www.rockbox.org/tracker/task/7652

I don't really like this solution though because I like to let Rockbox create my playlists for me by using the Database.

Here is my idea...

I don't really know how rockbox is put together, but what I would really like is a "Show ID3 Tags in Playlist" option that when turned on would cause it to reference the database information for that particular filename, and then instead of showing the file name display the tags from the database in a format that the user specifies with a "%a - %t" (for Artist - Title ) type string.

Is this a complicated pipedream?  I would think that the code that normally prints the file-name and playlist information could be modified to check for the "Show ID3 Tags in Playlist" option before it prints the filename or tag info, and if "Yes" would reference the database according to the format string and print that information accordingly, and if "No" would instead print the filename.  Seems like this wouldn't really change anything extraordinary, but I'm doing a little bit of assuming on how the play list printing actually works.  Seems like it would also require the database to be loaded to RAM too since it would probably cause a lot of disk read otherwise.

I heard there was apparently a version that opened each file instead of using Extended M3U, but I couldn't find anything about that and it seems like it would cause a lot of disk read.  If it referenced the database, one could avoid that by loading the database to ram.

I don't know, I don't think I'm the only one that would be interested in this though given the amount I see people referred to the Extended M3U solution.  I think this would be a better and more convenient solution though.

I guess you actually meant the ExtM3U support in FS#7652 [1]?

Yes, I'd love to have a tag-based playlist view as well. Using the database to query and format the tags should be even simpler than the patch in FS#7652, as no special file parsing is involved and there already is a formatting function.

Yeah, that is the one I meant actually.  Had the wrong link on the clipboard.
