I’m always amazed at the QUALITY and QUANTITY of excellent INFORMATION and ADVICE you provide here on this forum @Luke…
I’m a bit ashamed to admit, but I too suffer from PREMATURE ARTICULATION! 
Though previously it was apparent only when I whistled, sang, or hummed along to a song; I now realize my condition spills over as I jam along to songs with my harp.
It’s almost as if I just can’t wait to get to the next phrase, or in many cases the phrase I find most interesting in the song.
Listening to music previously I never gave much thought to the beats or the overall rhythm, now I can see why bass players and drummers are so important, they keep us in time when we wanna go Renegade 
.
I find myself sometimes getting the overall melody in a tune but then have difficulty keeping time with the actual song, or change the rhythm dramatically from one part to the next.
Before, I never really understood the importance of metronomes and/or clapping to keep time, but now realize how vital timing is to play along with a little love song, or any song for that matter 
.
Thanks @Luke, you rock
