Updated Snippet Feature
Snippets should be able to be added somewhere else besides the "info" section of a song. I think it would be great if snippets appeared under a song indented (with a snippet tag for clarification). This would be a great way to separate the difference between a melody and a snippet further.
Along with this, there can be a "snippets" category under an artist statistics. When adding a snippet to a song in the info section, it doesn't get included in an artists' song statistics.
I've also seen a lot of setlist with snippets (when played within a song) are listed as its own song or melody. For bands that play certain snippets often, this would be a great feature for better setlist!
