• Review links & update as needed

• Legal challenges
  • DRM
    • restrictions on circumvention (even when copies are legal)
    • technical challenges on circumvention (DRM can change even from disc to disc within a format)
    • future access to media which has DRM (such as when licensing bodies no longer exist & official or unofficial hardware/software is no longer maintained or available)
    • out-of-spec formats (for example, even if technical details on decoding CD audio are preserved, some discs may be unreadable due to tricks and intentional out-of-spec disc authoring)
    • newer hardware which lacks ability to read or decode older formats or which may not be able to enforce the correct output encryption (what happens to "official" DVD playback in the future when home formats have moved beyond HDMI/HDCP)
  • Copyright: restrictions on copying and distribution
  • Content owners change over time
• Logistical challenges
  • storage/organization of physical media
  • storage of digital media and required storage space
  • preserving discs which degrade over time
  • not all formats are easily preserved or played back (e.g. HDCD)
  • Other technical challenges: maintenance of codec libraries, software, preservation of hardware and its documentation/manuals
  • Differing regional releases (foreign/import versions with extra tracks)
  • Remixes, censored versions, radio edits, extended mixes, bonus tracks
  • Album art
  • Metadata (including CD-Text)
• Audio masters & archives
  • Legal ownership of audio masters
  • Physical format and condition of audio masters
  • Loss or destruction of audio masters
  • Loss of Myspace music deletion
• Censorship/Alternate edits
  • Music released only in censored form (e.g. some of D12's songs)
  • Versions of music videos without the censored version
  • Radio edits (not just censorship, but songs made shorter such as So Cold by Breaking Benjamin)
  • Single versions (such as Down by blink-182, where on the single version the song doesn't flow directly into the next track)
• Multiple versions:
  • Different release formats (Vinyl, MiniDisc, CD, etc.)
  • Different digital resolutions/processes (CD side vs. SACD side on a Hybrid SACD; DVD-Audio stereo mix compared to CD mix, example: 14 Shades of Grey)
  • Re-releases (loudness war)
  • Dolby NR on audio cassette tapes: detection and processing
  • Pre-emphasis on CDs: how
  • Promo versions: Angels & Airwaves pre-release/promo album version had changes to songs and to track order
  • Differences between released version and music video version
  • Differences in dynamic range in different releases of the same content (Loudness War)
• Handling of CD subcodes (copyright flag, pre-emphasis)
  • CDs ripped with incorrect pre-emphasis: detection and repair
  • Detection of HDCD (how is HDCD format signaled? Also add this to HDCD article)
  • Detection of HDCD audio ripped as normal CD audio, so that the user/decoder knows to use HDCD decoding
  • CDs replicated incorrectly (not gapless)
• Multiple formats (MiniDisc, CD, HDCD, DVD-A, audio on DVD, SACD, HFPA, streaming, HDtracks)
• Other formats/processes: Super Bit Mapping vs. the same release without it
• Note if any of these items utilize audio watermarking to trigger decoding modes (as opposed to digital "bits" or codes, such as CD subcodes)
• Gapless audio and its preservation / Gapless on modern platforms (such as Spotify, Tidal, and YouTube)
• Hidden tracks / pre-gap audio
• Fake lossless (ex. Tidal)
• Other streaming topics:
  • Master Quality Authenticated (MQA): not lossless, and also not well documented. Used in Tidal. And now defunct. If there was benefit to this format, what happens with its demise? (Additionally, and separately, details are needed on on MQA-CDs, potentially added to the MQA article)
  • "CD-quality" usually not being CD quality
  • Dolby "Atmos" and other "3D" or "enhanced" audio technologies for mobile devices or novel purposes, generally advertised for specific combinations of specific hardware, such as "Atmos" on Tidal on Android and its compatibility with "real" Atmos hardware such as Sonos Arc
  • Multiple versions of Atmos
  • Artists who are on Spotify/Tidal but where some of their music is missing, potentially leading consumers to believe they don't have more music or that the music is inaccessible
• Songs only ever released in low-quality lossy versions (such as iTunes & Spotify exclusives or MP3 files on enhanced CDs, or the Evanescence bonus track for Fallen for users who authenticated their physical CD via a browser plugin on a website)
• Surround sound
  • Songs mixed & released in surround sound
  • Songs mixed in surround sound for special purposes (e.g. film) but not released in surround sound
  • Songs recorded in mono and later released/remastered in stereo
• Dynamic video game soundtracks: Video game music that's responsive to the game conditions (such as location of player character in a level) compared to the soundtrack released
• Video game music stored as MIDI-style data that's "played" at runtime (ex. Super Mario 64): differences between the audio as played by the original device (ex. N64) and later devices (Wii, Nintendo DS); differences in the "official" soundtrack releases. Documentary/video on YouTube detailing this, find sources
• Music in a film or game that's not released on the official soundtrack, or differences between the "on-screen" and separately released music
