Help Loading songs from iTunes account

[Pooh434]

I have an online iTunes account with songs and albums that I'd like to download to my Dinc. Is it as simple as connecting my phone as a disc drive and copying the songs to my SD card music folder or to the EMMC(sp) memory in its music folder??? Please give me some general guidance before I mess something up. I hope the file formats are compatible.

Also, as I use Amazon and can use the Amazon MP3 app, I want to know if I buy a song/album from them, is it loaded to the SD card as music or the phone memory as music...or do you get to choose before downloading the file?

Thanks in advance for the help.
