Here's a link for the song
The Reason by Hoobastank.
Is it alright to ask for the key in which this song is played? I am a complete beginner and would like to create sheet music for this song.
The recording you linked is in E major.
This question may be of use to you: What does it mean to write a song in a certain key?
I would probably have closed as "too localized"--we welcome questions about specific music when it concerns a technique that requires some significant analysis (for example), but this one really doesn't.
