Where is the music eq that I downloaded at work for my music app?

why arent music eq that i download work for my music app?

So I have the soundcloud music app on my LG Leon LTE and every music eq app that I've downloaded/tried doesn't work with the music. Am I doing something wrong? On my old phone, I used to be able to download any music eq and it would work right away. Now it doesn't wanna work. Please help me out.. Thanks.
