Anyone got a link to a site or webpage where popular/pop songs are or can be translated into Irish ? Thanks in advance for any help.

Can't help you there but check out the cd's that are released every year around Seachtain na Gaeilge.They always include the lyrics even if you need a magnifying glass to read them. Some good stuff there, some not so good, but nothing you can't sing along to.
But I would suggest you try some translations yourself. I don't know if IMRO put on any workshops for people who would like to compose in Irish but it would be great if they did.
Mind you, I'm not too keen on the translation approach, I much prefer to hear a 'leagan gaeilge' of foreign language songs, and better still songs written in the Irish language.
Does anyone out there know if a rhyming dictionary 'as gaeilge'is available? I've been looking for one for years to know avail.
Hope this may be of some help!
