If you have wifi at home just install airdroid on the phone run it and it'll give you a link to type into your home computers browser, select the file browser, select the files you want to send and where to send them and sit back while they transfer to your phone.
Takes a bit longer than using a cable to copy but it's good for pure convenience, going to stay out of the what type of file it is debate but I'm sure google play will have a suitable player if the phone doesn't already.
