Dream Theater's new album/ cover songs

[longball11]

I'm wondering if any of you people heard any of Dream Theater's new songs on the upcoming album coming out in late june. They've released singles of Rites of Passage, Stargazer (rainbow cover), tenement funster/ flick of the wrist/ lily of the valley (queen cover). I'm hearing there is 5 cover songs on the new album? Who are they? Which songs are the best so far? I liked A Nightmare to Remember but its like 15 minutes long. I don't think i'll be able to buy it on iTunes because it'll prolly be album only for songs over 10 minutes long. And i hear that you can only get the cover songs on a special disc and there's a regular one without the cover songs?
Thanks for any info.
