do you have to mention the song you have mentioned in the musical features in general study?
No. I don't have my songs mentioned in the features in my general study. My teacher did a class test once on general study and I got 20/20 marks for the way it was.
I would advise u 2 because it will make it more clear for the examiner as 2 which of ur 2 songs the musical feature is relevant 2.
