The song “Happy Birthday to You” is song for singing and celebrating someone’s birthday.According to the 1998 Guinness World Records, it is the most recognized song in the English language in the world.Besides, I think it is translated to many different languages, which might also a reason why it’s so famous around the world. And maybe what some people listened in the first time is the translation version birthday song.I can’t remember when I first time heard this song, but I can still remember I felt very happy and warm when my parents and relatives sung the song and clapped their hands at the same time.From my perspective, I feel the birthday song is quite fabulous firstly because it can be sung with unaccompanied, secondly it could be easily arranged to different styles of music, which could be blues, jazz and even rock.I believe many people have the same feeling as me that although birthday song probably is not my favorite song, it’s a song we can hardly forget.
