I enjoy color palettes (I guess these are warm earth tones?), but I also like hot pinks and brighter colors. I'm not super into or early color palettes. I have a pink bathroom. I am not afraid of color.
Most of these do a very good job of letting the audience know it's about music and about the content. The placement of the types is probably my favorite part, though. Could experiment with illustrated designs like this or with more colour.
