Which era of Bollywood music is your favourite?

For me it's the 90s-early 2000s with Kumar Sanu, Udit narayan (the GOAT for me), Alka Yagnik, Sonu Nigam etc. dominating. 

I wasn't a fan of Himesh Reshammiya when he started to take over but looking back he and Atif Aslam were way better than the current shitty singers

Late 90s till early  2010s.

they days of kumar sanu or even udit probably in the 90's were good but much limited zone of music was happening and of same kind hey hey hey and la la la , ...they were one zoner singers so eventually led to sing those hey hey la la la love songs in bulk quantity , so yeah the best could be the time sonu nigam happened in mainstream as after rafi sahab and kishore kumar era if bollywood has seen the versatility and diversity of any artist work then it has to be sonu
