Hi there, AlanaMoore1.
It appears that you have some questions regarding an Apple Music subscription before subscribing, and we're glad to help with this.
Question 1: When you want to play music do you have to make a playlist and play like that or do you search it then play it?
Question 2: To play music or search it does it use data?
Question 3: Are there ads?
There are no ads included with Apple Music, but you will be presented with the different types of music you've shown you enjoy.
Question 4: Do you have unlimited skips?
There is no limitation on skipping songs. You choose what you wish to listen to, so it's your decision whether to skip or not.
Feel free to get back to us with any questions or problems you may have.
