The Wall of Songs premiered on last year's show and will be back this year and we have a peek at what's on offer. There are some amazing songs on the wall and, as always, some real challenging ones. David Bowie's Heroes? Come on. That's a friggin hard song to sing.\r\nHost Dermot O'Leary will unleash the contestants on the wall for them to grab the song they want to sing. As always, the songs are on the wall more than once. If more than one person chooses the same song they have to perform them together and the judges eliminate them. There are 140 songs in total including some of my favorites like Oasis' Don't Look Back in Anger and the Jackson 5 classic I Want You Back. Both super hard songs to sing. I should know, I've tried them both in karaoke.\r\n\r\nThe people who do a good job will move on to the next phase of boot camp. This is going to be one to watch. I look forward to seeing Grace Davies do something like Cheap Thrills by Sia.
