Samsung S6 Tablet. How to get permission for my mini SD Card

[Android Central Question]

I have lots of music loaded onto my mini SD card which I am using on my Samsung S6 tablet. However when I try i try to make some amendments to the artist/ song title it says I need to obtain permission. How in simple terms step by step terms, as I am not very technically able, can i obtain the required permission to enable me to make the amendments. one example is many of the artist groups like The Beatles have "The" in front of the group and its the "THE" i am wanting to delete
