Spotify is actually a really really good source for finding samples, ive been using spotify for quite a long time. They way to do it is
Search your word, And go to playlist
For example, sometimes my mind is just, dead. like, i dont know what to search for. Result?
I end up writing ''cool'' in the search bar and then listen through peoples playlist named cool.
aint that ''cool''? lol
Usually i type in genres or just some keywords and trust me, its a great tool !
