You can use media for educational purposes if:
- You don't share/publish it publicly on the internet
- You only use a small piece of the work (ex. a clip of a song)
- You got it legally (ex. didn't pirate it or get around a paywall)
- You don't provide a copy that allows others to avoid paying for their own copy
- You should cite anything that you use for a class, research project, or other academic work - because of academic integrity, not because of copyright.
