recording without bg music

Ok, I’m trying to record a cover for a song and Im using a headset and no matter what I try everytime I record on audacity it records the music IM listening to along with me.
Like I said, im using a headset, theres no noise coming from the speakers so why is it doing this and how can I make it stop?

Read this page and make sure that you are not recording using “stereo mix”. You need to have your microphone selected as the recording source and not stereo mix.
