This change adds a 'free-form' text genre to the existing `bear-id3.mp3` sample, and adds a new sample with a 'numeric' genre ([9 is Metal](https://mutagen-specs.readthedocs.io/en/latest/id3/id3v2.4.0-frames.html#appendix-a-genre-list-from-id3v1)). The samples were modified with: ```shell $ id3edit --set-genre "Gorpcore" bear-id3.mp3 $ id3edit --set-genre "9" bear-id3-numeric-genre.mp3 ``` Reading the numeric genre with `exiftool` shows the mapping back to 'Metal': ``` $ exiftool bear-id3-numeric-genre.mp3 | grep Genre Genre : Metal ``` The playback dumps don't contain the genre because it's not yet propagated to `MediaMetadata.genre`. That is done in a follow-up change. Issue: androidx/media#1305 PiperOrigin-RevId: 629043506
