Ná Féileacáin is a US-based, independent artist on SoundCloud that adapts Irish language music into English. There isn't much information on them or their work since they appear to be relatively new on the scene.

While by no means perfect, their translations are relatively close to the original texts. Some ... creative liberties... were taken in the case of "Dúlamán," but it does capture the basics of what's going down.

As far as I'm aware, CW has performed all 5 of the songs they have recorded.

Céad míle fáilte (a hundred thousand welcomes).

Pronounced (roughly) kayd MEE-luh FAHL-cheh

It's a common greeting or salute in Ireland.

On the street/in casual conversation, you're more likely to hear Dia duit 'Hello' (literally 'God to you') and the response, Dia 's Muire duit  (literally 'God and Mary to you').

If you're addressing a group of people, it would be Dia daoibh since Irish has a separation between the singular and plural 'you' forms, like French's tu and vous.

Here's the IPA for Dia duit broken down by dialect region:
/dʲia dˠitʲ/ - Ulster (Gweedore) (very roughly approximated to jee-ah ditch)
/dʲiə ɣitʲ/ - Connacht (Connemara) & Munster (Dingle) (jee-uh ghwitch)
This is close as I can get without IPA since the /ɣ/ sound isn't really found in English.
(https://en.wiktionary.org/wiki/%C9%A3 This does a better job of explaining this sound than I can.)

NOTE: In the Connacht and Munster dialects, it is possible for it to be written as dhuit and dhaoibh due to the final letter before it being a vowel. I believe both duit and dhuit are accepted by the Official written standard, but it's been a while since I checked so don't quote me on that.

https://www.abair.tcd.ie/en/ is an Irish speech synthesizer (like the voices used on Google Translate) that was built by Trinity College Dublin. You can just input the Gaeilge, and it'll speak it for you in the selected dialect.

Even these greetings are very slowly being phased out by the younger crowds in favor of things like Haigh
