Get musics/videos from itunes for free jailbroken ios 7?

So i want to download musics or videos(only music is fine too)from itunes for free, is it possible?
i know its not possible when not jailbroken but now that i jailbroke my iphone 5 running ios 7,
i think that its possible, but i did some searches on the net and did not find any…
the main reason i want to download from itunes on iphone:

1.has cover picture already, no need to add cover pics using pc or manually from iphone.

2.it saves the music in its original song/album/artist/singer name, when downloading from mp3skull or mp3bee it sometimes saves as tumblr3453 or preview751 etc which is annoying as i have to rename it using mp3tag.

3. As i lost my usb cable i can't connect to my pc, so i need to download from my iphone.(i have fileapp which lets me send files from pc to iphone over Wi-Fi, but pretty annoying as i have to turn on Wi-Fi each time)

so these are my conditions lol…
if its not possible from itunes, is there any tweak/app which lets me download music MEETING the conditions mentioned above?
any answers with descriptions/explanations would be much appreciated.

Well, there's a torrent app that can help you download music and store it in whatever file you want, but downladed soundtracks often have numbers on the files and may have the full info about the song when played.
also they should have the album picture. So yeah, try out a torrent app. But i could say you will have to wait for that stuff to download. Unless you have fast internet, then your fine.
