So yes, I just in fact made a blog post earlier about Alice Nine performing live for J Melo, and I'm here again to post another blog post!  On my first blog post earlier, I have mentioned you about Alice Nine's new song, Affection.  I'm writing this interpretation based on what I understand.  This is not the real interpretation, this is just my own.  So here it goes.

Buzzwords thrown about between love and hate
And overflowing on the screen
A common sentiment

3-2-1-0 start
But in this world there's no goal to be seen
Worn out emotions
C'mon C'mon C'mon C'mon (3x)

The time to speak vague words
is after dessert
If you want it
Get on board now
You're seeking it

To change the negative into positive
Across the ocean
This piercing passion overflows
C'mon C'mon C'mon C'mon (3x)

A voice addressed to no one
Transcending language and distance
The dots have connected and made a line
That represents affection

The same sound
The colors gather
Repaint the blue star

A voice addressed to no one
Transcending language and distance
The dots have connected and made a line
That represents affection


Explanation:

From reading out the lyrics and listening to their music, these are my interpretations that came to my mind:

So first stanza might represent the songs that Alice Nine has created.  The "songs" which are created with each of the band's "feelings" or "emotion".
2nd stanza tells us about how the band started with only the need to play music even without any assurance of what's ahead of them.
3rd stanza this time is how the band is starting to make a name even though the band hasn't "settled" in for "what" the band is and "who" they are. 
On the 4th stanza where everything is starting to get better.  Alice Nine's songs are being known to be inspirational or always having a positive effect the listeners.  So these songs' effects gradually spreading across nations and countries.
5th stanza first line clearly says that the "voice" is their music.  So you ca say that they create their music for everyone, not only for the Japanese, but also for the people around the world. "Transcending languages and distance" Alice Nine's music continues to spread throughout every country no matter how far or what language they have.  Because of Alice Nine's music, NUMBER SIXs get to know fellow fans around the world no matter what nationality they have, no matter what skin colors they have, no matter what religion they have. All of us are bonded with one love, and that is our love for Alice Nine.
On the 6th stanza where it says "The colors gather" I'm pretty sure it means different skin colors of different people around the world.  Because of our common love with Alice Nine and with their song or "voice", there's no more discrimination between different people around the world.  We forget our differences because of our bond, our affection towards one band and their music.

There you have it, my interpretation of Alice Nine's "Affection"   ☆*:.｡. o(≧▽≦)o .｡.:*☆
