‘Tis the season! Well, it’s nearly the season, anyway. A quick perusal of discounted Nintendo DS games at Amazon turns up a bevy of music-themed options, perfect for popping into stockings. All of the following ship for free if you have Prime:
Guitar Hero On Tour: Decades for $4.49
Guitar Rock Tour for $5.53
Jam Sessions for $5.92
Ener-G Dance Squad for $5.99

Or if you’d rather cook than jam, maybe check out America’s Test Kitchen: Let’s Get Cooking for $5.75. I say that’s a small price to pay to get your kids in there and making you dinner.
