You undoubtedly saw U2 perform at the pre-inauguration concert at the Lincoln Memorial in Washington, D.C. on Sunday afternoon, when Bono talked about how humbled and honored the band was to play for our new President Barack Obama, but make no mistake, the band is certainly taking care of its own major business in the form of its new CD "No Line on the Horizon," due for release in March. On Monday, as is customary, the band released its first single "Get On Your Boots," to Irish broadcaster RTE, before streaming it to the rest of the world via the U2 website and iTunes. The opinions were generally positive, and the new song was an instant megahit at home in Ireland and the rest of Europe, with Billboard magazine reporting that it's already number one in Ireland with two million hits, and number four on the U.K. charts with 12.5 million hits. So what does our music critic Mike Farragher think about "Get On Your Boots?" Here are his thoughts: "Unless you were living under a rock earlier this week, you already know that the U2 press machine went to work to get the word out on "Get On Your Boots." With words like "women are the future" and "I don't want to talk about the war between the nations," the track has social commentary linked with Bono's pillow talking about sexy boots. Even after listening to it a dozen times, I still can't say I warmed to the track. It seems like a bit of a rehash of glory days, with the cartoon riffs of their "Batman" soundtrack contribution "Hold Me, Thrill Me, Kiss Me, Kill Me," fused with the breakneck pace and scratchy riffs from "Vertigo." There are block rocking funk beats dropped into a bridge and a retro, bongo-like drum effect that keeps the track sounding somewhat fresh. I wouldn't say it thrilled me like "Vertigo" or "Discotheque" did when I first heard it, but it did sufficiently tickle my taste buds for new music from the band. Another early track that is getting a lot of buzz is "Crazy Tonight." "It's kind of like this album's 'Beautiful Day' - it has that kind of joy to it," Bono tells Rolling Stone in their latest issue. With the refrain "I know I'll go crazy/If I don't go crazy tonight," the magazine describes it as the band's most unabashed pop tune since 'Sweetest Thing.'"
