Something offering soporific stuff, like the music on the charts? (5)
I believe the answer is:
poppy
'something offering soporific stuff' is the definition.
I can't tell whether this defines the answer.
'like the music on the charts?' is the wordplay.
I cannot really see how this works, but
'like' could be 'y' (similar in meaning) and 'y' is found within the answer.
'music' could be 'pop' (pop music) and 'pop' is found within the answer.
A single letter 'p' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for poppy that I've seen before include "Flander's flower" , "catchy records like this" , "Flower of forgetfulness" , "Girl's name -- scarlet flower" , "Scarlet flower worn in Remembrance" .)
