How to delete downloaded tracks ?

[flobonni]

I know how to download tracks in my iPhone to play them without connexion but I'd like to know how I can delete them because it takes too many Mbits?
Thanks !

You'd be able to delete those saved songs by just flipping off the "download" switch!

Thanks for your answer but no...

I have about 20 saved songs

When the download switch is on, all the songs start to download (except these 20 already saved)

and when the switch is off these 20 songs stay saved (with the little green arrow).

There is no way to reverse the download process?

Thanks
