Yes, an exclusive, unheard voice is what people will be pleasantly surprised with. It’ll end up being a voice people will connect with and feel nostalgic about.
Some voices (singers) have curated themselves well by keeping themselves exclusive and unheard, waiting for a good song that connects with them.
Once the connection happens, the soul in the voice flows seamlessly, and the track/composition/song transcends to unimaginable heights. Those tracks are the ones that are always and easily remembered.
Don’t go for money, fame, or ‘opportunities’ – curate your voice. Feel blessed.
