Relishing Śrīmad-Bhāgavatam in association of devotees
Associating with like-minded, affectionate superior devotees
This verse from Bhakti Rasamrta sindhu answers all your questions.
Simple answer is no, it is not over attachment rather legitimate attachment, just as there are many sannyasis in our Iskcon acting as Spiritual masters, we respect them equally, however it is natural that one will be inclined towards one's own spiritual master (and like minded devotees). India is versatile for its spirituality. We aren't disrespectful towards others, at the same time we don't associate with them or limit our association. (Offer respect from distance and restrict our association, it means as Srila Rupa Goswami instructs us don't discuss/hear Srimad Bhagavatam or sastra from others)
A neophyte devotee has very little taste for hearing from the authorities. (srimad Bhagavatam 1.2.7)
In our Krsna consciousness society, there will be different categories of devotees and our society facilitates all people take to the process of bhakti and benefitted.
It is sublime for the pure devotees who are serious about getting in contact with the Supreme Lord, and it is easy for the neophytes who are just on the threshold of the house of bhakti. (Srimad Bhagavatam 1.2.6)
I came from south Indian tamil family, after association with like minded devotees I have developed taste for hearing and singing, even relishing Bengali bhajans or Sanskrit texts(I admit I haven't studied prabhandhas, I learned Thirupavai with the meaning, I am able to understand it because of being familiar with Srila Prabhupada's teachings) and understand them easily. It is matter of interest/ taste. These bhajans sung by acaryas are potent and transcendental.
Hope this helps
