Hey, so i know that the vocal melody is probably the most important thing when determining the key of a song (you don't want to be in a key that makes it hard for you to sing the melody).... But, do you ever transpose the key of the song just to intentionally mix things up? Like, if you post a song in the key of D or whatever, you'd probably not want the next song you post to be in the same key,right?  Do you think that's also something you should do when playing live (don't play two songs in the same key back to back)?
that is true, it is ususlly better not to have 2 songs in the same key in a row. and maybe i have actually transposed things a half step sometimes to directly avoid this, but not very often (and maybe never actually) but it seems strange to do this because the songs may be released in different orders on different platforms for different audiences.
