+Subject: [PATCH] avformat/id3v2: Add Grouping frame to id3v2.4 metadata table
+
+The ID3v2.4.0 standard defines TIT1 as the "Content group description"
+tag [1]. This frame is usually referred to as the "Grouping" tag and in
+de-facto use under that name by Vorbis and APEv2 [2].
+
+This commit introduces a mapping from "TIT1" to "grouping" in the
+id3v2.4 metadata conversion table. This will enable software to access
+it using that name. In particular, MPD will now read this tag correctly
+when using the ffmpeg decoder plugin.
