Will this transfer my music as well? Or just my apps and data?

If you mean restoring a backup from iCloud, if the music was purchased from Apple, it will be transferred to the oboe when you restore the backup. The same is true for videos and photos as long as they are included in the backup and you are not using iCloud Photos.

You’re welcome.

Autocorrect/predictive text got me again. I meant to type “will be transferred to the phone”, not the oboe. Geez, 😀
