In my head. I like to OD on my fav music. So when I'm at home I put the IPOD on REPEAT ALBUM and just keep it in my ears all night long. Therefore, it's literally in my head when I sleep. I love it. Right now I can't stop listening to Resistance. They remind me of a cross between Depeche Mode and Queen. Of course, they're way more Politically Minded than either of those bands. But that's okay. I'll love Muse till the end of Time.♥
