understandable if you mainly have moved to streaming apps, but if you dj as a hobby or pro you have a healthy collection of mp3s, wavs and maybe flacs. there is a lot of hobby and pro djs around the world for sure !

There are a bunch of apps that do this, here is one of the popular ones https://remini.ai/.

For more DIY you could use a comfyui or automatic1111 google collab or if you wanna go cheaper use a service like vast.ai and then search on youtube “face swap comfyui” or “face swap automatic1111” for a bunch of tutorials
