Could not find anything like this with the search function so here goes:

What is your absolutely favorite song of all time never to change no matter what with 99% certainty? It does not have to be Scandal, Scandal can be your favorite group but they don't necessarily have to hold your favorite song I'd say, especially not if your favorite song came out before Scandal. For me it is:
Do as Infinity - under the sun. I don't listen to it that often anymore but it will always stay my one all time favorite. My current favorite songs always change and after being listened to enough they don't have their initial magic anymore but this song is different for me, after all these years it still is at least 90% as awesome as when I first listend to it and that will stay that way.
Reasons:
-So much energy in this song, hard to explain what it is specifically about this song that makes it so great.
-Many fun memories listening to this song during online gaming.

Of all-time...that's a big order! haha
No matter what happens, I'm gonna say AFI's "Medicate". Some old school AFI fans might give me some flack about this since Crash Love wasnt their most...loved record. While I agree to some extent, I found Medicate to be that album's gem. IMO, it's a solid piece with all the elements of an upbeat, catchy, modern rock single. Both the bridge and guitar solo are something I'll never get bored of!

it sure is not easy to answer. I just know mine, 10 years of unchanged opinion about it should be enough to be really certain.

I cannot answer that...I bought my first record in 1959 so there are far too many to choose from !

70s' and 80s' hard rock.

K-ON!! - Cagayake! Girls

SCANDAL's HARUKAZE sir. I have too many reasons why, some even personal.

Even tho, I was born in 1996 still I would have to say, Nirvana's Come As You Are.
