A no good personality into crack — there's something for the criminal record! (7,3)
I believe the answer is:
gangsta rap
'a no good personality' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'crack there's something for the criminal record' is the wordplay.
I cannot really see how this works, but
'there's' could be 'n' (I've seen this in other clues) and 'n' is found in the answer.
'crack' could be 'gag' (both can mean a joke) and 'gag' is present in the remaining letters.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
This explanation may well be incorrect...
'into' is the link.
Can you help me to learn more?
(Other definitions for gangsta rap that I've seen before include "Aggressive macho music of US black origin" , "style of music" .)
