Mmm... You would make a mistake If you think I'm not awake I know what's goin' on You've been lying to me But I don't want to set you free I know what's goin' on I'm the one who makes you happy You got to know that for sure Come on can we give our love just one more try Make it better than it was before Did you try to resist Was she longing to be kissed I know what's going on You have changed who you are I been watching from afar I know what's going on Mmm.. I know what's goin' on Mmm... I know what's goin' on Does she whisper, does she sing Does she say you're everything I know what's goin' on I can see it in my head When we're lying in our bed I know what's goin' on I'm so angry I could murder, oohh And I'm so lonesome in my mind Oh, how I wish I didn't love you baby But you got me hangin' on your line Mmm... Mmm... I will wait for this to end Cause I know you'll need a friend When at last she breaks your heart Cause the only way to win Is to get you back again Until then I'll fall apart Mmm... I know what's goin' on (ad lib to end)
