Query: the greatest 80s band......

a-ha is just brilliant.... this band changed the game of sound in the 80s and 80s videos with just one song.....'take on me' is my favourite 80s song of all time....this song has the illest beat of all time... i love the instrumental break.... i love the way he sang the song... and the video....MASTERPIECE!!!!i heard alot of 80s bands have one hits an they disappear... too bad a-ha was one of them because this album is great....'train of thoughts', 'blue sky', 'hunting high and low', and 'love and reason' are classics and should have been hits.... i understand that the first single had the best sound...i wish bands like a=ha were still round making great music....masterpiece....
