Right now there’s really nothing that you can do about it, but it seems that come iTunes 12.5, users will be able to actively “dislike” songs. This means that if there is a particular track you don’t enjoy, you can choose to dislike it which will then tell iTunes that this isn’t what you’re after, and hopefully it won’t recommend such songs in the future.
Songs that have been disliked will also show up with a broken heart next to it so that if you’re so inclined, you can go ahead and skip the song. iTunes 12.5 is currently in beta and is part of macOS Sierra that should be released later this fall alongside the operating system, or alternatively it could also be released with iOS 10. Either way it isn’t available to users just yet.
Some other features of iTunes 12.5 includes some sorting/categorizing features for classical music lovers.
