Phase issues can easily be tested by using both a mono test tone and a stereo test tone. Or by using the test files located on this website: Online Stereo Polarity (Phase) Sound Test
Since your problems occur at the same time in the aforementioned songs, it is more likely that your files could have a problem, or whatever source you are using could have bad files. You mentioned you are using Airplay. I don't own any Apple products, but I assume Airplay is a wireless technology, based on Bluetooth. In this case, Bluetooth adds additional compression to the already compressed files.
