It happens to me that i have songs twice in a playlist. The reason for that is that spotify treats the "same" song as two different songs if they are from another album (for example).
It would be nice to have an option to show songs which titles occur more than once in a playlist.
This way you could easily delete doubles.

Hey there @Daniel_S,
We haven't heard back from you in a while about this idea. In this case, we'll go ahead and close this idea for now since we don't have any additional details in order to give it a proper status.
However, you can always submit a new idea with more details like @Peter suggested if this is still something you'd like to see in the app.
Let us know if you have any questions, we'll be happy to lend a hand!
Have a lovely day 🙂
