FOUR, 1D's latest album, which was released not long from today (17 Nov 2014 released), and this album showed quite some change from these boys.

So far, although I'm not really in to 1D's music, I do have to admit that they really have talents in making good music. Now, let's start off with the leading single from the album, "Steal My Girl".

I was surprised how this song turned out quite good, and I really like the pop-rock music. Although I would prefer songs with deeper meaning, this song still got me categorizing it "Good". You can watch the MV HERE!!!

The second single, "Night Changes", was 'popper' than the previous single, and to be truthful, it was a fun song to listen to. The album, in overall, is edgier than most of their previous works, and they have somehow improved their music styles. Most of the songs in the album are pop-rock styled, like; "Girl Almighty", "No Control", "Act My Age", and many more. There are also slow-mid tempo ones like "18", "Spaces", and "Clouds". It was an enjoyable album to listen. For pop-rock lovers, this would probably suit to your taste. Overall, the album is a really good one, and might probably, sooner or later, burst into fame.
