You're welcome to submit them on the relevant movie, episode, or game page. They will be subject to user voting, like all other songs submitted on the site. 

Please do not submit your songs if they have not actually appeared in the show or movie. This is a violation of the Tunefind Community Guidelines. Only confirmed sync placements should appear on a project page while all other songs will be deleted as incorrect entries. Accounts caught spamming are subject to being deleted without warning. Artists caught maliciously spamming will be placed on Tunefind’s blacklist and potentially banned from appearing on the site.
