Prepare for some couch-dancing, Idoloonies! That is, if things go well on tonight’s disco-themed performance episode of American Idol. Of course, if the top 7 are stupefyingly uncreative — or limited to the same tiny list of songs the Idol producers seem destined to hear on the show over and over and over — then we’ll be hearing three Donna Summer tunes, three tracks off the Saturday Night Fever soundtrack, and Danny Gokey’s cover of “Grease.” And I’ll be dialing 1-800-Head-in-the-Oven! But why choose pessimism when blinding, delusional optimism can keep a spring in your step till Ryan Seacrest gets all up in your face come 8 p.m. EDT? Here’s my Disco Night request list for the remaining finalists. Ch-ch-ch-ch-check it out, then post picks of your own in the comments section below.
