Whether you're a fan of Enya, Sinéad O'Connor, Damien Rice, The Cranberries, Thin Lizzy or Van Morrison, you owe Ireland a debt of gratitude the next time you rock out ... or whatever it is people do while listening to Enya's music.
And that's not even considering the phenomenon that is Celtic Woman. Those angel-voiced Irish lasses could sign the phone book on PBS and we would give it a listen.
No. 2: Guinness and Jameson
It seems stereotypical, but when something tastes as good on your lips as Guinness or Jameson Irish Whiskey, it's hard to argue its rightful place on this list.
What trip to Ireland would be complete without visiting the Jameson distillery in Cork or the Guinness brewery in Dublin?
Thanks to the work done there, millions of people across the world can enjoy a "pint of the black" with a Jameson chaser.
Both of these tasty beverages can trace their roots back to Ireland in the 1700s. Centuries later, they are still being enjoyed not just at home, but worldwide.
With Jameson selling more than 31 million bottles of whiskey annually and 1.8 billion pints of Guinness enjoyed worldwide each year, you'll hardly be alone if you enjoy a bit of true Irish cheer during our No. 1 selection …
No. 1: St. Patrick's Day
What began as a religious celebration honoring Saint Patrick and the arrival of Christianity in Ireland is now more a secular celebration of Irish culture in general.
And you don't have to be Irish or even Irish-American to enjoy it in true Erin go Bragh spirit. That's "Ireland forever" in Gaelic-Irish.
These days, St. Patrick's Day is probably the most widely celebrated saint's day in the world. In Ireland, it became an official feast day in the 17th century, but it's nearly as big in America, Argentina, Japan and Australia.
All evidence in New York City and Chicago to the contrary, St. Patrick's Day is still not quite a legal holiday anywhere in the United States.
But whether you are Irish or Irish at heart, you're sure to find plenty of company should you choose to wear the green or toast sláinte, or good health, with a pint or two come St. Patrick's Day.
