Why am I not able to set music as my text message notification?

[Latisha Lucas]

A white screen pops up whenever I try to add my personal music as a text message notification on my LG aristo.

Which version of android?
Which carrier?
Which texting app?

What is the exact wording of any error message you are getting?

Notification sounds are usually found in the "/Notification" folder. (The capitalization is important.)
