heya! not sure if this will help but from the chord progression you can discern the key and mode the song is in (eg D lydian) then just find the easiest place to play this (on guitar it'd be the 1st pentatonic box starting from 10th frett - adding in the 7th and #4th to make it lydian) then with these 7 notes sing the melody and pick along to find the vocal melody (if disonant vocals try neighbouring notes outside the mode too).. not answer to your question but might help..
he makes interesting point about ease of making music today - ie download a DAW and a few drum sample packs and midi in a quantized guitar riff and autotune some vocals.
there are way more songs being made available today so more than ever talented musicians hell yes ..but also coz of this tech 'easy route' a lot of people who are maybe just popular kids but havent spent years learning their instrument or songwriting who get to the top of the charts not because their music is particularly fresh or inspiring.
agree with vibe of your comment tho that we can be more affirmative and 'yes and' eachother he just wants clicks, i like rick
