I just purchased exactly the same song from iTunes and Google Play Music to compare them. If you are interested, here are the differences.

Google Play Music

MPEG Layer 3 (mp3) Stereo 44.1Khz

320 kbits/sec

9.34MB

 

iTunes

AAC Stereo (L R) 44.1Khz

275.5 kbits/sec (I assume it’s variable bitrate)

8.06MB

 

iTunes uses AAC, while Google Play Music uses mp3.

They both use a high bitrate.

I can’t hear any audible difference.
