Hi Greg/Debra. Yes assuming music content was a problem. Did some research re Warner Music Group, WMG. Edited new tracks.(Please note the artist name for 2 of the tracks. Couldn't help myself!) Now in mosquito fb site https://www.facebook.com/groups/126390337427802/ complete with spelling errors. Fixed them but not going to re-post as it takes hours to upload. As suggested by Gary M have contacted Tim S to pass on and post onto Mosquito web page.
Thanks for your information and suggestion.

PS: After reading Wikipedia and WMG, does Facebook have the same music copyright issues as YouTube? All a new process to me.
