Music is a collection of hearable feelings.
Some nice feelings can be got because of simple music, mostly called Top 40/ R&B/ Commercial music.
The feelings-part of these songs are on the upper side of the song itself, not literally. You don't have to think, to listen very hard to get into the feelings.
The problem is, that the feelings THAT you get by listening to it, are not very 'deep', not really thought of, quite ordinary.
But, if you spend more effort in listening, and GOOD listening, comparing etc., you will discover the same feelings, but amplified maybe a 100 times. At first it cost a bit more effort, but you get really more back.
For example; you are very sad. (ahhh...). You start listening to a R&B song. You got the feelings, and feel good for a moment. When the song is over, you're still sad.
You listen to a song, where time and effort had been put in, something like Dream Theater. (my opinion). You hit play, wait for the song to build up, then ... comes the climax! Here, you've reached, let's call it point X. Point X is an amplification of the feeling you already got, same like when you used drugs. You could have a 'bad trip': You WERE sad, you become soooo sad, you're always thinking about suicide, if you were happy, you are simply TOO happy. Then, the song starts to go to his end (listening to Dream Theater, that will last some time...
), and point X is fading away. What rests, is a satisfacting feeling. You lost your sadness, or got a controlable version of your happiness. Could be compared with sex? Yes, probably.
So: what's a good song?
When trying to make good song, there could be billions of advices about song structure, verses, bridges, chorusses etc. etc., but as you see, the most important thing IS: put all your effort, all your abilities, your entire heart, in the song.
well,
that's it.
