Ringtone not pausing music

[zachthebomb13]

I just switched over from a Samsung Note Edge to a Nexus 5, and have been super happy. However, there is one thing that I just noticed today that is weird. When I'm listening to music and someone calls me, the music keeps playing, and there is no ringtone. I have almost missed a couple of calls because of it. Any ideas on how to fix it? This is my configuration:

OG Nexus 5 on most recent update from Google
Not rooted
Completely stock
Using Google Play Music
Using headphones plugged into phone (not bluetooth headphones)

That's strange. Do you have it set to Priority Interruptions, or No Interruptions? If not, then see what happens if you wipe the cache partition: http://forums.androidcentral.com/nexus-5-rooting-roms-hacks/352008-guide-nexus-5-recovery.html. Be aware that this can take up to 5-10 minutes on a Nexus 5.
