Dubolt Range Input

Working on a playlist generator. I really wanted to get granular with the data used to generate the playlists because I've gotten very particular about the tones of a playlist, and the more popular playlist generators don't really seem to get that granular even though the Spotify API supports it.

I've chosen to make the inputs ranges instead of needing to select a particular point in a plot because I feel that values like tempo, dance-ablity, and energy are too broad when discussing all music to force a particular choice. I've also decided to have a bit of fun with the range labels.
