Yes and no.
These credits never expire and rollover from month to month
Credits you've purchased a la carte (outside of subscriptions)
Credits you've earned from participating in our A|B song feedback program
Free accounts and subscriptions come with credit limits; these credits don't rollover
Standard accounts come with a 1200 credit limit which resets monthly
Pro accounts come with a 4800 credit limit which also resets monthly
Free accounts come with 10-daily / 100-monthly credit limits
If your subscription is canceled, your account will revert to the free-account limits.
Think of your credits like monthly mobile phone data. If your phone plan provides 10 GB of data per month and you only use 4 GB in January, the unused 6 GB typically doesn’t roll over into February. Instead, your data resets, and you start fresh with a new 10 GB allowance.
But why?
This allows us to offer particularly generous limits while still balancing our server loads to provide reliable service for everyone.
