I believe the answer is:

charismas

I'm a little stuck... Click here to teach me more about this clue!

'star qualities' is the definition.
'charismas' can be an answer for 'qualities' (charisma is a kind of quality). I am unsure of the 'star' bit.

'help primarily in securing many album sales' is the wordplay.
'help' becomes 'char' (I am not sure about this - if you are sure you should believe this answer much more).
'primarily' indicates taking the first letters.
The initial letters of 'in securing many album sales' is 'ismas'.
'char'+'ismas'='CHARISMAS'
