I am currently using Spotify on a phone with 8GB internal memory and no SD card. I cannot use an SD card due to work restrictions. It would be a good idea if the Spotify app allows purging of cached songs without have to wipe both cache and data at the same time

Your idea was submitted a while ago and unfortunately didn't receive the amount of kudos needed to stay active in the ideas board (100 Kudos per year).
In order to keep the Ideas Exchange clearer I'll close this idea for now, but this doesn't mean Spotify rejected this idea.
If you think this is an idea which needs to be implemented, you're welcome to post it in slightly different again :)
Have a nice day!
