If this really shits you Brutal, register your songs with apra & ask them to get in & fight for you.
APRA is free & collect the the $ from radio stations every time you are played. You also get a payment for every gig you play. @ the end of the financial year they just divi up the money made & disperse it to ea members bank account.
This helps pay past band members who have written songs & legally deserve credit for them. Ea song has it's own listing so past members get paid when their material is played & current members get paid for their contribution of new songs.
Stops legal hassles down the track if you make it big hahaha.
