managing music on new samsung a5

[Android Central Question]

I synched my samsung with itunes and all my music was downloaded onto my new phone via smart switch. Which I didn't really want it to do. I must have clicked a box I didn't mean to. Sigh.

Now I want to remove lots of the albums as its killing my memory. I can't do it from google play. How can I download checked albums from itunes?? Using Smart Switch it looks like I can only synch contacts and calendar......
