Discounted Credits for Seniors (65+) and Veterans

Description: A user suggested offering additional monthly credits (e.g., 20 credits/month) for users who are 65+ or veterans, especially those on fixed incomes. The idea is to make Songer more accessible to hobbyists and older musicians who may want to experiment more with song creation without worrying about using credits too quickly. For example, being able to hear more than just a verse and chorus before spending credits would help them explore their songs more fully. User Context: Some users, particularly seniors and veterans on fixed incomes, may want to create and test multiple song ideas but feel limited by the standard credit allocation. Suggestion: Consider introducing a special discounted plan or bonus monthly credits for verified seniors (65+) or veterans.
