Songs on guys cheating on girls?

My boyfriend is cheating on me and I have this big competition coming up. I want to sing a song about how he hurt me, but I'm here to hurt him back. Songs like 'Better Than Revenge' by Taylor Swift and 'Begging On Your Knees' by Victoria Justice. Songs like that. I want something to show him I know, and I'm done with him. As many songs as you can give me would be great. Thank You so much!
