Lauren AlainaIt was a night of wall-to-wall music on a special Tuesday installment of 'American Idol'.

With but a single hour to pack in three rounds of competition between Scotty McCreery and Lauren Alaina, there was hardly time to even get judges' comments, much less create emotional moments.

For the third round, though, Alaina managed to do just that with a perfectly suited song. Jimmy Iovine chose the song, which we're told will become her single if she wins the season. We have a feeling it might just get released even if she comes in second, though.

The song is 'Like My Mother Does,' and ironically was released first on seventh season finalist Kristy Lee Cook's album.
