iPod touch Record Output Audio Without Cable?

I've been searching on the internet for this for a while now, maybe a week, and I haven't found anything useful. So I came here, made an account, and got to work, because I've solved multiple issues with my iPhone and iPod from this site. You guys are helpful.

Anyways, I'm in to this artist, Bjork, and her new album 'Biophilia' came out on the 7th of October, and there's a certain song on there that I just don't like, because of some drums. Yet, she has a different version of that song on her app, and I want to record it without using an external microphone.

I don't want to spend $20+ on a stupid 'male-to-male' cable. My iPod runs on 4.2 something firmware, it's jailbroken through GreenP0ison. Any jailbroken app is possible, and any official iTunes app is possible, as long as its under $5.

Please help, I really want that version of the song. Bad. Love you.
