Problems with Symbols, High Severity (9)

	Change	Effect
1	Type of return value has been changed from njbid_t* (4 bytes) to void.	1) Applications will not obtain a return value and execution may change. 2) Layout of parameter's stack has been shifted by 4 bytes because the hidden first parameter (return value) has been removed. All the parameters will be incorrectly initialized by applications.

	Change	Effect
1	Parameter songid of type njb_songid_t* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	3rd middle parameter codec has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Parameter folder of type char const* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Parameter songid of type njb_songid_t* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	3rd middle parameter codec has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
3	4th middle parameter title has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
4	5th middle parameter album has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
5	6th middle parameter genre has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
