Lá, as we all know, is the daily Irish newspaper, and is now one of the first all-Irish Podcasts. Cheak it out, I now subscribe to it, its what it is, theres no music, just some one in Irish reading the news. Im sure if more people listen to it, and more money goes into it they'll be music and stuff.

Theres also another Irish Podcast, I cant remember its name, but just type "Gaeilge" into Podcast search engine and it should come up.

There are several.

http://imeall.blogspot.com/ is one.
