I personally dont like any of these.
W/e is a mockingjay perk and you can get mockingjay from treasure hunter.
LogBlock is unneeded imo as its really easy to be careful who you trust onto your plot. Also with the new /grief command you can stop griefs instantly. Not to mention the sheer size of creative would create a lot of data that LogBlock would need to store.
To add real music to your plot just make a texture pack that changes what each disc sounds like.
