There’s a few semi-hidden features on Shfl. Whenever I want to be able to do something I add it in and usually stick a keyword into the search bar. The search bar is kinda like Shfl’s console. Anyway, here's a rundown of some of the more interesting things you can do, you can try them out in the search bar to the left (on top if you're on a phone).
if you type in a year, like 1975, you'll see an option to restrict the albums to ones that came out in 1975. This also works for decades, just tack on an ‘s’, like ‘1960s’. Then you can flip through, say, African music from the 1970’s.
There’s a few categories that I rarely want to see, like children’s music or christmas music. These are still in the database but will generally only show up if specifically searched for. These categories are ‘Christmas’, ‘children’s music’, ‘stage/screen’, and ‘comedy’.
If you type ‘streaming’ into the search bar, four options will come up: ‘on bandcamp’, ‘not on spotify’, ‘not on apple’, and ‘not streamable’. If you select one of these you can flip through albums that satisfy those criteria.
