Feature Request: More metadata for audio files!

[shirok1]

Would be great if we can display following properties from the menu (following naming is from ffprobe -v quiet -print_format json -show_format xxx.flac):

• album
• album_artist
• artist
• date
• genre

PS. even better if there be a "guide"/"checklist" for adding an additional property, so that we can diy and contribute back!

BPM also!
