From my perspective - It's pretty dull. Absolutely nothing interesting harmonically, no polyphony in melodies, very little use of interesting timbre, no development of themes, very repetitive. I don't really like this song.
My favourite songs/bands
Basically anyone who can pull off interesting melody, harmony and/or timbre and decent development of a piece of music. (Alkan, Chopin, Liszt, Rachmaninoff, Above and Beyond, Hallucinogen, Astral Projection...)
I'm sort of like @giblit - I don't really like music with lyrics, I can't understand them when sung unless I really concentrate (don't know why), though I am fine when the voice is used as an instrument itself, as in as a seperate melody line.
I generally prefer music from the Baroque and late Romantic / early 20th century eras of music, people like J.S.Bach, Ravel, Debussy, Brahms, Saint-Saens, etc.
Don't mind all the hating. (None of these guys are happy here.)
I rather enjoyed it. Though, it won't necessarily go on my "to keep" playlist...
Hard to define. I don't like heavy metal or hard rap. Or the Beach Boys. Other than that, it's typically on a per-song basis.
I do enjoy classical, waveform, a lot of electronica already mentioned above, good country (not that horrid country rock), Enya, Enigma, Asia, David Arkenstone, Kitaro, uh, Evermind, Nirwana, uh..., The Mamas and the Papas, uh, lots of stuff. (Maybe I should go take a look at my music racks and come back?)
Can't say I can really get into Happy. As has been mentioned I think it's too repetitive, ironically it doesn't evoke the emotion advertised.
I _am_ a fan of The Cat Empire, one of my favourite songs https://www.youtube.com/watch?v=QsgBtSCnUMU
I'm also a massive fan of Meatloaf and have been since early high-school.
When I program, I listen to instrumental, jazz, or classical. I tried programming while listening to music like "Hey Mickey", "Enter Sandman", "I Disappear", "Puttin on the Ritz", "I Would Do Anything For Love", etc., but kept finding myself singing along instead of programming. Outside of programming, I will listen to all of it.
I'm also familiar with Lindsey Stirling's music. Very powerful.
