The producer says he has to hand it to the consumer, as it's the cost of getting Liszt on the radio

'liszt on the radio' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'the producer says he has to hand it to the consumer as it's the cost of' is the wordplay.
I cannot really see how this works, but
'he' could be 'price' and 'price' is found in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
The remaining letters 'lis' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'getting' acts as a link.
