Chanting
If after years of chanting we still have no taste then we have some problem, either with hearing the Holy name or with our level of surrender.
Effect of Chanting
One need only chant the Hare Krishna mahamantra. Everyone engaged in the practice of chanting the Hare Krishna mahamantra will be completely cleansed, from the core of his heart, and be saved from the cycle of birth and death.
Srimad Bhagavatam 7.6.1,
Srila Prabhupada.
Becoming A Perfect Chanter
Drink more and you become a drunkard. Similarly chant more and you become a perfect chanter.

Purification by Chanting
The chanting itself purifies us and as the heart becomes purified, the Holy name is revealed to us as being non-different than Lord Krishna.
Easiest Process of Meditation
Chanting of the Hare Krishna mantra is the easiest process of meditation in this age.
