Foreign Languages - Which One To Learn?

As you may or may not know, I've wanted and even started to learn Scotts Gaelic.  Unfortunately, there is so little information about it that I've come to the conclusion I would do better learning a different language.  I don't like it, but I will have an easier time acquiring the materials to learn German instead.  So, German it is.

To mark the occasion I've decided to share my (at this moment) favorite German song, Klavier by Rammstein.  In case you wondered klavier (klav•ier) means piano.
