How to add music to iTunes library on computer with Cydia?

I know about Mewseek and have used it before but when I plug my iPod into my computer so I can transfer all the music from Mewseek to my un-jailbroken IPhone, all the music from Mewseek gets deleted. Is there any way to get free music to stay in my iTunes library on my computer so I can transfer it to all of my Apple devices (preferably with Cydia)?
