Can i revert all changes i've made on a iTunes song?

As part of Lady Gaga's countdown to her album's release i've downloaded Born This Way, Judas, Edge of Glory & Hair. Overtime i decided to organise to put all four tracks into a made-up album so they are all in one place. I no longer want this, and i want each song to be back into the original album, with the title, etc that it came with. Is there any way i can simply revert changes i've made to tracks on iTunes?
