The Wiki Entry for the getStatus method

Using the form of mp3.getStatus().state is not a good idea in any code. Every time you call getStatus() it communicates to the chip in this case, in other similar uses it could be far worse. Don't assume these calls are cheap. Call it once and store the results then use the results.

Why did you think you needed the single quotes around DfMp3_StatusState_Paused? DfMp3_Status.state is an enum. Search for how c++ enums are used.

DfMp3_Status status = mp3.getStatus();

if (status.state == DfMp3_StatusState_Playing)
{
}
