I started listening thinking, okay niiice vocal.
I ended listening thinking, wow, that's good!
It's actually a great vocal, well sung, lovely clarity.
Nice rising hook in I think the second line of the chorus.
Really well put together track without any unnecessary bells and whistles.
The ONLY thing I might suggest altering is the line starting cling to your rock, which felt ever so slightly squeezed in. Maybe clinging on would flow better?
Anyway, great stuff Tom.
