I hope you do want genuine feedback... From listening to your sound clips, I'd say you are certainly able to sing and play, but you could do with better material. Irish- American pub music (note: this is notIrish pub music)is not my area and the audience you are aiming for may love the songs you do, in which case take no notice of my opinion. But

"I'll tell it to you with me brogue
So I sound like I come from I-re-land
I may have never bin there..." makes me cringe, as does the fake 'brogue'. I would suggest you find some real Irish songs, (there are plenty that haven't been done to death, available right here on the Mudcat forum and in the Digital Tradition database) and sing them in your own accent.

Sorry if this isn't what you wanted to hear.
