CosmicMusic.swapAndLiquify(uint256) (#1435-1468) performs a multiplication on the result of a division:

CosmicMusic._prevTotalLiqFee (#899) is set pre-construction with a non-constant function or state variable:
- _totalLiqFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.7 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
