Its a custom project that I made myself. https://vinylify.com/ I made it on here and they are pretty expensive to get done. (Around $120 USD) I posted the music I used with the voicelines on soundcloud I can link that here in a moment. You are welcome to use my sound files and make your own copy. Its fun to do. If you use my files just give me some love on the post and come back when yours comes in to show me! Source: about 1 year ago
