If your music taste really is all over the place, chances are, your Spotify "Daily Mixes" are way too concentrated on one specific genre.
Personally, I listen the most to music that would technically fall under rap. However, I'm really not a huge fan of lyric-dense, repetitive sounding songs that lack intonation and melody.
I spend hours listening to rap albums and playlists only to pick out the few gems that barely sound like rap. It was only overtime that I've adopted new methods of finding those gems in a more timely manner. Because impatience usually gets the best of us, try these tricks when your most recent playlist starts feeling a bit dry.
To avoid this, I dig through Spotify's pre-made playlists to try and find ones that are more a hybrid of genres or generally upbeat sounding and download them.
When I have serious down time, such as in the shower or car, I give them a listen and add all the songs with even a remote chance of being good to a playlist. Even if you don't like it off the bat, if a song catches your attention (in a good way), save it for later. You'd be surprised how much potential some songs have to grow on you.
If you like genre-less music that causes you to stutter and resort to "all types" when asked about your music taste, I feel you.
Add a few songs that are similar enough to fit into the same nameless category, and that you actually really like, to a new playlist. At the bottom of the playlist, you will see a list of song suggestions. You can listen to them for a few seconds, and either add it or skip it. When you get through all of them, just hit refresh. Before you know it, you'll have an entire playlist filled with songs you would have never been able to look up otherwise.
Now, the main problem I have with Spotify's "Daily Mixes" is that they're quite literally full of music that I've already saved. Listening to them as a way to find new music can be incredibly counterproductive, but there is a way to counter this. Download all your playlists.
Yes, even the ones you've overplayed to the point where you'd rather listen to nothing instead of hearing those songs again. The goal is to download practically every song that you wouldn't consider to be new music when you hear it. Then go to your "Daily Mix" and add every song that is not marked as downloaded to a new playlist. You can remove all the old stuff from your downloads afterwards, because now you've identified and sorted all the new songs that Spotify thinks you'll like that you don't already know.
Then have a listening party!
