Making ads for companies that might use songs

Assalamualaikum, I am a 3D artist and I recently started searching for clients that I can freelance for but I am confused what kind of clients should I work with I mean I know I can't be working with businesses that make haram products so that is in control. But when I make the ads for those companies I do not add any audio but they might add some kind of song or maybe add some haram elements later in the future. So I just wanted to know if it halal to be working with those businesses. Thank you :)
