The three latest albums I've purchased are as follows:
Stronger - Kelly Clarkson.
Mylo Xyloto - Coldplay.
Own The Night - Lady Antebellum.
I'd definitely recommend "Stronger" to anyone, such a great album. It's different to the old style of music Clarkson used play, but it's not completely changed, there's still a touch of her "Breakaway" days present throughout the album. It has a country/pop/rock vibe, similar to that of Taylor Swift (a bit more rock, with a stronger voice, but nonetheless, similar.).
Mylo Xyloto is a bit.. odd. It's good, don't get me wrong, but it definitely wouldn't be to everyone's tastes. "Princess Of China" ft. Rihanna is one of the most mainstream tracks on the album, followed closely by their previous hit "Every Teardrop Is A Waterfall". There's a lot of controversy surrounding the album, with complaints from other artists that Coldplay have plagiarised many of the tracks on the CD. Overall a good listen, but there's no slow tempo track similar to "Yellow", "The Scientist" or "Fix You", which is a bit of a downer.
As for "Own The Night", well, Lady Antebellum definitely wouldn't be to everyone's taste. They're an American band, mainly country music with some pop influences on their music. A similar style of music to Shania Twain, Taylor Swift, etc. "Just A Kiss" is probably the most recognised song from the album, because of its chart success. Definitely listen to it if you're open to new types of music.
