Track Origin

• Relates to the track's composition, meaning its publishing metadata
• Only one of 3 options can be selected:
1. Original Work
   Your composition is original: you are not reusing someone else's composition (melody, lyrics, and structure). Note that while a remix often reuses the original composition, it is considered an original work if it substantially alters the original recording.
2. Cover Song
   Your song is a new performance of a song previously recorded by someone else, and you are not substantially changing the original composition (melody, lyrics, and structure), or reusing part or whole of the original recording.
   Note that recordings with lyrics translated into another language, or with lyrics substantially modified (including adding lyrics to an instrumental track) are still considered covers (even if they additionally qualify as derivative works).
3. Public Domain & Traditional
   Any music whose copyright has expired or is otherwise free of copyright. This also includes traditional songs and melodies, as well as any non-original religious music.

Track Properties

• Relates to the track's recording, meaning its master metadata
• Multiple options can be selected (or it must be indicated that none of the options apply):
1. Remix or Derivative
   A new version that alters an original recording. Any derivative work, including modified versions such as sped-up, slowed-down, boosted, nightcore, etc. A remix can be produced by the original artist or by another artist/producer. Note that covers with translated, modified or added lyrics should also be identified as derivative works due to the modification of the lyrics.
2. Samples or Stock
   Any recording containing samples or any stock music, be it a royalty free beat, or any loops from a sample pack or music creation software.
3. Mix or Compilation
   Any form of mashup (multiple track segments joined together) or medley (multiple full tracks joined together), as well as any track in a DJ set/mix or compilation (which does not have the same ISRC as the original).
4. Alternate Version
   Radio edit, extended or shortened versions, as well lofi, live or remastered versions.
5. Special Genre
   White noise or sleep music, ambient, new age or meditation, karaoke or instrumental, classical (in the sense of older music like Beethoven and not contemporary music in the classical genre) — or any other similar genre where your recording is likely to be mistaken for another recording.
6. Non Musical Content
   ASMR, sound effects, nature sounds, speech, spoken word, podcast or radio show.

• Cover Song: Requires a mechanical license when distributing to iTunes or Amazon in the USA, and to any DSP for certain other countries (more information here).
• Samples or Stock: If your track contains a sample, then that sample must be cleared through a master license. Stock music (also known as "royalty free music") is almost always provided with an inherent license, but you should make sure that this is the case. 
• Remix: Requires a master license from the rights holder(s) of the original recording. Furthermore, if your recording is based on an existing song whose lyrics you have translated or significantly modified, in addition to a mechanical license, you additionally need a license from the original lyricist.
