Upasaka Kalpesh Mange,
as told be others here, it's at large distruction for the mind, and given your intent here, you should best be sure about it.
How ever, even for monks, while my person nevertheless likes to give much appreciation to it, musik or singing, that increases or gives rise to samvega, is not unskilfull perse. For serious lay people the use of what is called smot, a special style of singing and proper text, is very usuall here in south east asia, and a specially used on occations of going forth, to increase gratitude toward parents. Usually giving a possible liberating lake of tears, being about suffering and taking leave at most.
But also this can become a distacting issue, if clinging on the pleasure of sound and certain upcoming emotions.
Singing yourself (even in mind), even if smot, especially when monk, is not as skilfull to be seen, and hardly bring on a base where it does not gets against certain precepts, if taken.
So, as mostly everywhere, one is also left alone here, to be honest about ones intent.
