Clarifications & Notes

The primary philosophy is simple. There are two things I really do not want.

First, I do not want other people deriving financial or social benefit solely from work that I have done. Just taking the work I have done for personal gain feels disrespectful. However, once someone puts their own spin or creative effort, that concern goes away. As an aside, I also do not like reuploads because they tend to have lower audio quality which undermines the music.

Second, I do not want the music being associated with video games that are not TETR.IO. The music was handcrafted for the game, and I really value that context being associated with the experience TETR.IO provides. If other games were to use it, it would dilute that context.

Here are some additional notes:

• Commercial use includes any use that directly or indirectly generates revenue, including advertisements, subscriptions, sponsorships, paid access or sales. Donations unrelated to the music are not considered commercial use.
• Attribution should follow the TETR.IO Branding Guidelines. In addition, the song names must be written correctly, and the artist must be listed as "Dr Ocelot" (please do not include a "."). If the video is on YouTube, you can also tag @doktorocelot.
• As always, the fair use doctrine may apply in situations. If it does, these terms are irrelevant to your use as it is not subject to copyright protection. Note that fair use is decided on a case-by-case basis, and it should actually qualify based on the four factors.
• If you are not sure whether your use qualifies as "background music," ask yourself whether viewers would primarily come to watch your video or merely to listen to the music.
• Remixes may use portions of the original recordings, stems and/or compositions, but must be transformative and may not be represented as official releases. Essentially, it must be something a reasonable person would consider the remixer to have put in substantial creative effort. To put it another way, it has to be something that cannot be easily replicated by anyone. For example: nightcore, slow/reverb, etc., are not considered transformative.
• Recreations are considered transformative remixes.
• It is important to note that songs that merely "take inspiration" are not considered remixes and thus are not subject to these terms. As in, these terms are irrelevant to that case as it is not copyright infringement.
• Live covers include every possible live cover. For example, playing the songs on an instrument, playing the songs in a band, playing along with the original recordings, etc., are all considered live covers. Performances are considered primarily an expression of the performer, not the composer.
• Reuploads to social media sites are not permitted. This includes compilations, extensions (i.e. 1‑hour versions).
• A "rhythm game" is a game whose core gameplay consists of reading and performing a chart: a predefined, music-synchronized sequence of input events that is scored based on the player's timing accuracy relative to those events.
• Licenses for non‑commercial rhythm games would not cost money. However, a license is required to ensure that TETR.IO and the songs are not misrepresented. Licenses for both non‑commercial and commercial rhythm games are extremely likely to be perpetual.
• Creating a rhythm game as user-generated content for another game, such as Roblox, follows the rule of "Use in rhythm games as a part of the base game."
• If you wish to use the music for a game that strongly ties said music to TETR.IO, such as representing TETR.IO as a product in another game, please contact us because you may be able to get special permission.
• osk has the right to sublicense the songs without going through me. If you received permission from osk for whatever reason, you do not need to contact me.
• For any use not explicitly listed above or for further clarification, please contact me at my TETR.IO email address.
