There is no language for music. Music is common in all languages. If the tune is good we can enjoy the song irrespective of the language in which it is written. An animal will also understand the music and dance accordingly. It may not know the meaning but it will enjoy the tune.
Personally, I enjoy the songs written in my mother tongue that is Telugu. If we know the meaning of the words we will enjoy the song very well. Even though I understand English and Hindi songs I always prefer Telugu songs especially light music and Karnatic music. But I hear Tamil and Kannada songs also once in a while.
But it will be always easy and added benefit to enjoy the music with its meaning and feel if we know the language also. Then it is easy to learn and byheart the song. In that regard I like songs in Malayalam, Tamil,and Hindi more.
Mostly I like the melodies and those which are semi-classic. The fast ones and the beat-ones I like as a variation and change once in a while just as tasting pickle or salt after taking a few cups of kheer or dessert, just to reinvigorate the taste for next sweet dose.
My friend who is a retired Judge of Tamil Nadu once took me to Mysore Datta Peetam on the way of our legal work in Bangalore. There we heard the speech of Holi Shri Ganapathi Sachtananda Swamigal for 45 minutes. Though we do not know Kannada language, in which Swamigal delivered His speech, we understand what was his communication. Holi Shri Ganapathi Sachtananda Swamigal of Mysore Datta Peetam made a research on Healing through Music. He released many albums on this.
Recently I read Sudha Ragunathan Madam, a famous Tamil Carnatic Musician started a project on 'Healing through Music'.
I love songs in which the name of any musical instrument in Tamil
1. Thunbam Nergayil Yaazhisaithu Nee Inbam Serka Maattaayaa - Kanne (When I am in trouble, won't you play the violin and make it pleasant, O Girl)
2. Veenai Kodiyudaiya Vendhane, Sangeetha Sow Bhakyame (O King who bears the Veena on his Flag)
3. Singaara Punnagai Kannara Kandaale Sangeetha Veenaiyum Ethukamma (When we can see the beautiful smile, why should we have a Musical instrument Veena)
No life without Sun
Knowledge is power.
