Let's be clear, the songs are good, really good, Adele's singing is fantastic. The album's sound though, is pumped up, exaggerated, unreal and ultimately very tiring to listen to.
I'm not referring to the arrangements or the musician's performances or the recording/production. I'm aggravated beyond belief by the mastering (and probably therefore, final mixing). You just cannot get beyond 3 tracks in succession without your ears feeling like they're being water-boarded. Ouch.
If everything's 10/10 flat out - sooner or later, someone wants to be at eleven!
It's the same with the movies. Take a delightful 'flat' artwork illustration like the original Tin-Tin books and read the stories that unfold within both the words and the pictorial representation. Then experience the Spielberg/Jackson movie version. It's a bombardment - relatively. Non-stop action with almost no thinking time, no space to linger and feel things. Hollywood throws out the same ethos through both sound and vision - everything maxxed out all the time.
