A captive audience got to hear new music from Carrie Underwood this week. The singer revealed that she’s at least partway through recording her new album, and that baby Isaiah is a big fan.

“Played some of the new music this morning for little Isaiah and he smiled from ear to ear the whole time," Underwood writes on Twitter. “I think we're on the right track!”

Isaiah Michael Fisher is now eight weeks old. The “Little Toy Guns” singer has kept a low profile since his late-February birth, although she did step out for a Nashville Predators playoff hockey game earlier this month. Husband Mike Fisher plays for the Preds, who trail the Chicago Blackhawks three games to two in a best of seven series.

So far, Underwood has only revealed one picture of Isaiah. One month ago she shared a pic of him snuggled in a thick blanket, holding on to a mini-hockey stick while he slept. She’s staying off the road until June 26 when she plays Ozark, Ark. There's no announced schedule for when a new single or new album may become available, although in the past she indicated that both would come in 2015.
