good morning, I would like to ask if it is possible to include in the next system update, while listening to A SINGLE TRACK from your music library on the SSD / HD, the possibility of being able to DELETE it if you don’t like it. 
thank you so much
In case of music stored on an SSD or USB external hard drive
It cannot be deleted directly from the device or the RoseConnect App.
You can remove them from the list by selecting and deleting the music source in the SSD folder shared on your PC.
It is impossible to copy from an external pen drive or ssd to an internal hard drive SSD, but you can copy or delete sound sources in the PC to the SSD built into the Rose device.
Please see the link below.

Thank you
Thank you, unfortunately I know this function well and in fact it is the ONLY way that allows me to delete the tracks I want but it is a very INCONVENIENT function given that it would be enough to put a simple function on a “curtain” directly on the track being listened to by the RS150B with the note written “delete single track from your SSD”. I understand that “saying it” is easy while “doing it” can be difficult but this would be a very useful function.
