Digital Music Releases

I find that I am purchasing more and more music in digital format only. There are a number of reasons for this, but this is not what I want to discuss today.

With the switch to digital distribution, there are several things missing that I would like to see corrected.

  1. Liner notes.  The digital music package should include both a cover art image as well as either a PDF file with the liner notes insert or HTML equivalent.
  2. Cover Art.  I haven't seen a problem with this, but the cover art is an absolute requirement.
  3. Playlist file. If the music files are meant to be played, they should include a playlist file such as M3U.  This is a nice-to-have feature.
  4. ID3 tags.  I have seen MP3 files that do not include information such as title of the song, artist, track, attached to the file.  This is commonly known as meta-data.  If the files do not have ID3 tags, then the user won't be able to identify the album, track, or artist when the songs plays  on the music player.
  5. Multiple formats: 
    1. MP3 with 320 kbps bitrate is absolute minimum.
    2. Wav file is useful to avoid any kind of loss, but Wav files are huge.
    3. Flac file format is a compressed kind of wav file.  Flac offers the same lossless nature of Wav files at 66% to 50% of the size of the original Wav files.  The downside is that Flac files are also huge in comparison to lossy formats like mp3 and AAC.
    4. Mpeg 4 Audio (M4a-AAC) is the standard format for Apple iPod devices and is supported by iTunes.  There are two distinct subtypes of Mpeg 4 audio:  enclosed in Mpeg wrapper (M4a) and enclosed in native AAC ADTS wrapper (AAC).
    5. Note: DRM generally won't impress music buyers.
  6. Song names that naturally sort in play order:  "nn - title.mp3" is one good example, where nn is the track number and title is the name of the song. If the track number is not a part of the name of the song, it makes it difficult to play the tracks in the proper sequence, unless you have a playlist file.  Playlist files were my item #3 above.
  7. Accepting payments with PayPal is nice.
