Without doubt, my favourite album is This Is Acting by Sia. The album is mostly composed of songs written by Sia for other pop artists that weren't included on their albums. Putting in like that, it seems as if these songs couldn't cut the mustard. However, the album did reach top 5 in several markets, including the US, UK and the artist's native Australia.
The album consists of upbeat pop rhythms and motivational lyrics, conveying the will to overcome one's fears like no other album. Moreover, the singer's vocals are incredible throughout the album, delighting the listener with each note. The title derives from the fact that these songs were written by Sia as if channeling other artists. For instance, the lead single Alive was originally co-written with Adele and Tobias Jesso Jr for Adele's third album and it's based on her life, not on Sia's. Even if it's rather commercial music, the album is considered concept music and this is partly because the artist has never given up her own ideas and ways, regardless her success.
In short, having greatly overcome the initial rejection of its songs, this pop, energetic, album shows us all how real it is that failure teaches success. This is an album for daydreamers, for people who need to build confidence, for every high achiever in any aspect of life really.
