Methods and systems are presented for selecting a preferred source of ratings (e.g., Metacritic.com) and integrating the ratings into the electronic program guide (EPG) such as displaying the ratings alongside program listings. By allowing the user to select the source of ratings, the media guidance application ensures that the ratings provided are meaningful to the user. The media guidance application retrieves the ratings from the source of ratings selected by the user and displays the retrieved ratings in the corresponding program listing so that the user may make an informed decision about his or her television viewing. The media guidance application may also incorporate the retrieved ratings into media guidance functions such as setting reminders, scheduling recordings, or recommending programs.
