I have read all the comments, and there are a number of things that I must state here.
My introduction to CM was through abhangs. I started out listening to them, and then started listening to more "traditional" CM songs from other great artists. If it had not been for Abhangs, I would have never known telugu, sanskrit and tamil songs that are part CM.
It is not easy for a complete novice to appreciate CM songs. Also Indians are now spread out world over and it is difficult to find someone who has the patience to help a novice understand the complexity and beauty of CM. In such an environment Abhangs act as an important doorway, an easy point of entry from where one can then move on to other treasures of CM.
North/South -
South Indians think that Maharashtrians are North Indian. Marathi language falls under the Indo-aryan classification, but does not automatically make them North Indian.
The question I ask is this - Does language alone define a region? In fact culturally Maharashtrians have more links with the South than the North.
Vithala is a god revered both in Maharashtra and the South. Purandara dasa and Tukaram both wrote about Vithala. There are many other gods that have a huge following in Maharashtra and South India.
Also Maharashtra's geographical location means that there has been ample intermixing already.
In fact, I believe of all the Indo-Aryan (I did not say north Indian because that tag really does not apply to Maharashtrians fully) language Marathi is best suited for CM. Use the link-

Ok, now coming to the purist, traditionalist aspect of the discussion. CM has the power to accept new ideas (like violin, saxophone, guitar) without sacrificing the soul of the music. By this I mean, new ideas are not just taken but changed to suit CM. This also happens with abhangs, where the style of singing is such that it looks natural. Anything that does not suit CM will just not survive beyond the first concert!!

I believe in future we will have Maharashtrians singing very good CM. In fact Maharashtra could be a source of new audiences and talent for CM.
CM always stands to gain form exploring new grounds. It is everlasting, it can take care of itself.
