I would like to ask someone how long it would take to learn
those 2 songs and some tips on how to play them ^^:

The beijing cocktail

They aren't too hard ^^ but hey.
How long it would take me to learn or for you to learn?

That was a different Feb08er that threatened to suck you off
I remember that

Sadly, I was the threatened.

Let it be known that I concur with everything this gentleman says, ever.

The Blackout and Blessthefall? Nice choice!
Anyway, I don't think they'd take long at all to learn.
They're both quite easy songs.
