Unsurprisingly, U2 -- who aren't just Ireland's biggest band, but one of the biggest bands in the world -- are on this list with three separate songs. One of those is "Sunday Bloody Sunday," their moving, angry meditation on the 1972 Bloody Sunday incident where 26 unarmed civilians were shot by British soldiers in Northern Ireland.
Also appearing with three songs are Dropkick Murphys, the Boston punk band that proudly flaunts their Irish heritage. The Pogues, another raucous Celtic rock outfit, appear here twice, as do the more soothing sounds of Ireland's own The Cranberries (who are here with "Linger" and "Zombie," a favorite on Halloween playlists, too). Another welcome '90s pop throwback? B*Witched, although the Irish girl group's most played St. Paddy's Day song, "C'est la Vie," ironically has a French title.
The Dubliners are also doublin' up on this list, cropping up with their Pogues collab "The Irish Rover" as well as "Molly Malone," a generations-old Irish tune.
That's not the only modern version of a decades-old ditty, though. Celtic Woman's version of the immortal "Danny Boy" is here, as well as Metallica's take on "Whiskey in the Jar."
One entry that might give you pause is House of Pain's 1992 hip-hop hit "Jump Around" -- that is, unless you know the video. Yes, the group hails from California, and no, their signature hit has nothing to do with Ireland, but the music video was shot during the '92 New York St. Patrick's Day Parade.
Similarly, while Great Big Sea are Canadian, their folk sound draws on hundreds of years of Irish heritage in Newfoundland and Labrador, thus their inclusion.
