Tonight's episode of 'American Idol' is all about the rock and roll.

To honor the genre, the remaining nine contestants will each sing a song from the Hall of Fame's 'Songs That Shaped Rock and Roll' list, which includes over 650 tracks.

Which songs should they sing? PopCrush has put together a list of their suggestions. Read what they had to say about 16-year-old hopeful Lauren Alaina:

Lauren Alaina: It'd be all too easy for Alaina to sing Aerosmith's 'Dream On,' since she has that "thing" with Steven Tyler and did so during her audition. The teen should show off more of her countrified side and have a go at Patsy Cline's classic 'I Fall to Pieces.'
