I agree that Hayko's entry would have been much better had it been sung fully in Armenian, the Armenian part is what lifts this song to higher heights.Armenian entries 2006-2010 all are at the same level imo. My vote got Jan jan and I believe Anytime ya need could have been breathtaking had it not been sung in English.
I would add that also André's entry would have sounded much better in Armenian.
I don't agree they were all on the same level though, imo 2008-2010 entries were in their own league.
The workmanships of the 2006, 2008 and 2010 entries were pretty similar. I like them but they are not exactly particular; especially the sound of Apricot stone was too lightweight/mellow for my taste albeit I acknowledge the composition's quality. Also its first version was better imho. No par and Anytime ya need come closer to my preferences but they suffer a lot from the English language. After a while I got used to it in the former but in the latter it still really disturbs me. Probably because it reminds me of the beautiful Joksimovic ballads.
