Euskaltube is the Basque youtube, a personal project of a dynamic guy, Haritz Rodriguez. Now that the site is one year old, he's dared to add audio (mp3) archiving and sharing capabilities now to its website. I don't know if copyright zealots will let him fly free, but I am very much glad that such a platform exists now in Basque.

I've tested it with some tunes, and it works nicely. You can share the files using its flash player, but also letting others download the mp3. As an example, here you have a couple of songs than I once mentioned in this Cemetery. A basque lullaby, Pello Joxepe, performed by Paco Ibáñez was plagiarized by Naomi Shemer in Israel, where it's a very well known patriotic tune, Yerushayalim shel Zahav, Jerusalem of Gold.

This is Paco Ibañez signing it (Imanol Lartzabal helps him):

Download both from here and here, check for Audioa eskuratu, that's where the mp3 files are.
