I will try my review (not so easy in english cause of technical words about music and stuff).
Dead Inside : I really like it, especially the second part with the guitar and vocals. It makes me some shivers, like Madness in T2L (it has been already said) -> 9/10
Psycho : Big riff and electric guitar. Love it and I guess it will be huge in live -> 8/10
Mercy : Not a fan at the beginning but as many Muse songs, more you listen it, more you like it. Too much synths to me -> 6/10
Reapers : One of the best song of the album (and even of a lot of albums). Huge heavy guitar part, good vocals, genius solo (isn't the longest solo Muse has ever done ?), apocalyptic outro. In live, it will be awesome as well -> 10/10
The Handler : I love the structure of the song and the tempo variation, the entrance of the guitar, moves of the drums and vocals, you really seem somewhere else when you are listening to Matt. Like Reapers, one of the best Muse songs (but already said in many reviews) -> 10/10
Defector : At the first listening, I was not able to think anything about this song but now, I really like it. I think it is the one which is the nearest to Drones spririt, anxious and opressing -> 9/10
Revolt : I think people are tough with this song. It is obviously not the best Muse song but there are some interesting things. I like tempo variations and the lead vocal -> 6/10
Aftermath : Very nice love song. The guitar intro and back are beautiful. I guess they could have put the guitar louder back to the vocals, and less synth -> 8/10
The Globalist : Huge song but I expected more than that (maybe because I just heard it was the "After CE"). Whistles, guitar intro, heavy part, piano outro, everything is good -> 8/10.
Drones : I have absolutely no idea about what to think for this song. I was very surprised. I will have to listen to it many times before like or dislike it. For the "surprise", I put a 6/10.
Overall, I really like this album.
The first half (from Dead Inside to Handler) is very very good. Near to perfect.
The second half is calmer and a lot of variation, less guitar.
Muse did not lie about the "back to the beginning" with a lot of heavy parts and a lot of guitar in every songs (except Drones of course).
I'm sure the Drones Tour will be awesome and some songs which will be great in live.
Drones : 8/10
