Eva Cassidy – Wade in the water Lyrics 24 days ago
Whatever the command "Wade in the water!" means, the speaker really wants it to happen, and for children too, since it is repeated several times. The warning/notification "God's a-gonna trouble the water" also happens repeatedly.

Two primary interpretations:
1. "Wade in the water" means escape from slavery (which might require literally wading in the water to save one's skin). A modern day version is to advocate for Black civil rights. "God's agonna trouble the water" means there could be negative consequences of this.
2. "Wade in the water" means the escape of the Israelites from the Egyptians via the Red Sea in the book of Exodus. "God's agonna trouble the water" means once the Israelites have escaped and the Egyptians have followed God will make the sea fallback and destroy the Egyptians.

The line "Look over yonder, what do I see? The Holy Ghost a-comin' on me" has a common meaning referring to death that inevitably ends a human life, eventually meeting with God (The Holy Ghost/Spirit being one of the Holy Trinity making up the divine). Another commonality is "band dressed in red" can mean potentially bloody or lethal consequences for whatever wading in the water is and when God troubles the water.

Each primary interpretation has different symbolism for the concepts in the song:

First interpretation.
Children = black children.
Host in White = lynch mobs or the Ku Klux Klan out for blood (or take back their property).
Israelites = white people who support slavery or oppose Black civil rights, or anyone who supports White supremacy.
Are the Israelites the Chosen People? No.
Israelite leader dressed in white = leader of lynch mob or Ku Klux Klan (Israelites are Semites, not Black).
Band dressed in red that Moses led = Anyone who fights toward being redeemed.
Being redeemed = Escape from slavery or improvement in Black civil rights.
Follow me down to Jordan's stream = an exhortation to the listener to take steps or help others toward being redeemed.

Second interpretation.
Children = israelite children.
Host in white = Egyptians.
Israelites = Egyptians (Egyptians are Arabs, might be visually similar to Semites to the naive observer).
Are the Israelites the Chosen People? Yes (although deeper analysis beyond this song indicates they aren't the only ones).
Israelite leader dressed in white = Pharoah (leader of figurative Israelites).
Band dressed in red that Moses led = Israelites. Moses has association with red (e.g. blood smeared on doorposts for the passover).
Being redeemed = Making the way to the Promised Land.
Follow me down to Jordan's stream = the river Jordan is the eastern border of the land promised to the Israelites, so maybe directionally this means going to the Promised Land.

Kermit the Frog – Rainbow Connection Lyrics 24 days ago
The central question of the song is the question "Why are there so many songs about rainbows?". Visually a rainbow is a vision, an illusion, and has no trickery about it. The speaker has heard there is a connection there, and the speaker knows others believe the connection exists. The speaker doesn't think the interpretation he's heard makes sense, but he thinks he (and others) will figure it out some day.

A related phenomenon is the idea that morning stars are capable of granting wishes. Someone had to be the first to think of that idea, and that idea was spread around from person to person and generation to generation. The speaker observes that the concept of wishing upon morning stars has been productive, but the speaker does not understand why people go stargazing or what they get out of it.

However, the speaker does feel SOMETHING related to rainbows, and presumes others can feel that too. His best guess is it's magic but is not certain. One manifestation of this phenomenon is hearing voices in one's head in a semiawake state. The feeling is analogized to a song heard by sailors (maybe the temptation song of the siren). The speaker has felt this feeling a lot and feels it's an intrisic part of who he is, but he's only willing to say that someday we'll figure it out. The speaker separates himself from lovers and dreamers, indicating it's a categorization relevant to the question.

My answer is it is the psychological concept of apophenia (https://en.wikipedia.org/wiki/Apophenia). People make connections between rainbows/stars and other entities because of the natural human tendency to perceive meaningful connections between unrelated things. The emotion of wonder (https://en.wikipedia.org/wiki/Wonder_(emotion)) is also an explanation, but I don't like that as a full explanation because not everyone has that level of emotional range. My interpretation is the lovers and the dreamers can feel wonder, but the speaker cannot. But I feel like everybody could feel apophenia if they try.
