Hello. My school system is trying to get me to use the google play store instead of iTunes. . Is it accessible on the iPhone? Also, they are telling me about some device from google that hooks to my stereo in which I can use the google play store to play music from it. I'm sorry I don't know the name of the device. Maybe a chromecast? I do have an older stereo system in my classroom. I am a music teacher and it is imperative that I use something which is quick and easy to use. Do you think this device might be accessible? How about my itunes library on my mac? Can it be converted, discs as well, to the google play? I want to use my I device. I'm trying to explain to them that this is what is most accessible for me. Currently, I am putting music on it and using my bluetooth remote which I absolutely love. Are there other accessible devices that work with google and the iPhone to stream music? Your thoughts? Thanks.
