'below-par' is the definition.
I can't judge whether this defines the answer.

'album i stop playing' is the wordplay.
'playing' indicates an anagram.
'album'+'i'+'stop'='albumistop'
'albumistop' anagrammed gives 'SUBOPTIMAL'.

Can you help me to learn more?

(Another definition for suboptimal that I've seen is " under par".)

I've seen this clue in The Telegraph.
