Issue with Initial Volume Level after "Up Next" in iOS 8.4

Hi,

I've noticed that the volume of normal playback i.e. existing playlists, albums or artists is fine following the update. However when I add a new song "in real time" using the new "Up Next" feature I notice that the volume for the first few seconds of the inserted song suddenly goes louder before settling back to the existing level. As I have the sound-check feature enabled which tends to reduce the volume of most modern songs, I'm assuming the initial loudness is due to the sound-check value not being applied in time before the song starts. Anyone else experienced this? I couldn't find anything else on the internet about this.

Thanks,

Simon.
