It's a toss up between Hands Held High & In Between. On another note, if they polish up No Roads Left it will be one of LP's best songs! edit: Just realized that Sucre06 necroposted :/
Yeah, he's becoming notorious for that :/ But I'll say that In Between is my favorite song that features Mike on the song.
I'd have to say HHH, I love the way Mike sounds and it's such powerful verses...the singing he does at the end is beautiful too.
