not when Songlike is broad and may concern form rather than melody.
warm
melodious
when the sound is pleasant and musical
not when Melodious is praise and does not simply mean related to melody.
warm
tuneful
when a melody is pleasing and easy to follow
not when Tuneful evaluates appeal, while melodic can neutrally describe structure.

theme-led
when recurring melodic themes organize the work
not when This technical phrase is not a standard substitute outside analysis.
formal
cantabile
when performance should proceed in a smooth, singing style
not when Cantabile is a specific musical direction, not a general synonym.
literary
lyrical
when flowing, expressive melody resembles song
not when Lyrical can describe prose or emotion and does not require a clear tune.

melodic line
The flute carries the melodic line above the quiet strings.
melodic phrase
Each melodic phrase ends with the same rising interval.
melodic structure
The song's melodic structure makes the chorus easy to remember.

Melodic describes relation to melody and is not always praise; melodious or tuneful is better when pleasant sound is the claim.
