Having the lag here as well, although I initially thought it was just Amazon Music being silly because that does happen.
And then when I was reading through the thread I realized that the audio QUALITY in my headphones has drastically decreased. I was hearing it and thinking maybe the headphones were going back but then I took them home and connected them to my other iMac that is not updated and the sound was crystal clear again without any crackling or skipping.
I can still deal with it since I am only listening to music when I'm at work but if the quality continues to go downhill I'm going to be SOL because I work in a shared office and I NEED my music but I have to be able to move around a bit.
ETA: I have August EP650 bluetooth headphones and I'm working off a late 2010 iMac here at work. Ya know, I tested on my old iMac but not the new one I just got last month that I did update to Yosemite.
