Talking about Miley Cyrus's video "we can't stop"

It was a big shock when I first  watched it, I wondered what the hell is that supposed to say to the fans? That the real Miley is a b##ch? I mean the video doesn't even match with the song, the song is good, good lyrics, instrumentals etc.. but the video is a drama! It was supposed to show teenagers having  fun, good time, parties  all the time, but this one sounds like: " hey look at me I'm Miley, I grew up now, I'm done being that little girl you knew in Hannah Montana. This is  what I really  am a teen who likes partying and  doing the b##ch.
What do you think?

Talking About One Direction's new song and video "Best Song Ever"

First, I will talk about the song. It's a good song, good lyrics, instrumentals and voices, amazing! But once again Harry and Zayn or Zack :D, sang the whole song while Louis, Niall and Liam sang 2 phrases each other. That's not fair, I mean, I'm not a directioner and neither Louis, Niall and Liam's fan, but if they keep giving the whole song to Harry and Zayn, we will never discover what the other members are vocally capable to do. Harry has the lowest voice of the group  and he hit most of the "high notes" in the song, do they want to destroy his voice? Louis who has the higher voice of the group  stayed in the middle range, Niall whose voice is higher than Harry's stayed in the lowest range, and , maybe for the first time, Liam sang some high range of the song. Zayn was ok, he sang in his range.
Now let's talk about the video. I didn't understand what it was supposed to say to the viewers, was it talking about a boys band who want to stay what they are, or was it talking about a boys band who met their soulmates in a place where there was this song they named best song ever? I'm confused. The song talks about a guy who meets a girls in a disco, i don't know where, with a love song playing, but the video talks about something else. Please explain me :/

Talking About Jennifer Lopez's Song "Live It Up"

Last year we listened to the brand new Jennifer's song "On The Floor" and we all know it was an amazing song, it had a big success, it was a summer hit. This Year she tried to do the same with "Live It Up" but it didn't work, a big failure. Why so? The lyrics, yes bad lyrics can ruin a whole song and that's what happened to Live It Up, the lyrics don't match with the song. It would have been a great song if it had talked about a break up between a girl and a guy, the girl is happy about that because she was tired of this guy who took a joke of her for a long time, now she can't wait to start a new life.
