[5] Wall of Soundz was originally going to be released as a side-project that McFadden embarked on with American songwriter and producer Robert Conley, known for his work with Australian singer Darren Hayes, but both decided that due to the variety of tracks, McFadden should release it as his third solo album.

[6] McFadden also spent time in Los Angeles working on the album, and this is where he met up with American rapper, Kevin Rudolf, who provides guests vocals on the song, "Just Say So".

"[6] The album also features a collaboration with Amy Meredith lead singer, Christian Lo Russo, on the song "Not Now".

In an interview with Music Theatre Australia he explained, "I wrote Mistakes after the album was finished, but it turned out so well Rob and I made it fit with the rest of the record.

Kylie Northover of The Age gave the album 3½ out of five stars and stated "McFadden has dispensed with the boy-band balladry – for the most part – and enlisted American producer Rob Conley to create some safely synthesised commercial dance beats over which he can croon.

"[10] Garrett Bithell of SX News gave the album a negative review and stated "Unfortunately the material on offer here is very generic electro-pop, filled with so much auto tune McFadden’s vocals are often quite indistinguishable".
