Ok I'm making in fact done with an app (my first app , it's a trivia quiz app of a boy band) and than I realized that it using copyrighted images and music could be bad for the app! So I removed all the background images and I'm using insta pictures of those band members (which are obviously not copyrighted and I doubt the members would mind it lol) anyway the problem is the music part there is a section of "guess lyrics" and a song is played (not more than 20 seconds). The company is big and I doubt they would even respond to my email! what can I do to avoid this issue? I'm all ready to give credits of course! changing pitch of the sound is it going to help me in this case?
