Any idea's?

You need to have Sirius XM login to be able to stream music, but the link is https://player.siriusxm.com

it does not appear to happen when streaming Pandora

Any ideas on what this could be?

For some reason while streaming music it plays extremely slow, as if it were in slow motion. This happens on 2 completely separate systems, one in a corporate environment and one in a home environment. Both running Opera 42 currently, however the problem only appeared in the last few days. At home the songs would cut off after about 15 or 20 seconds, i then watched it upgrade to version 42 and then it started playing slow.
