Would it be just safer to launch the song Sveglia la Sera under a new artist name using the same account I tried launching it under the first time?
→ Yes, that’s the best solution. Just make sure that this iMusician account is the only one you’ll use from now on (close the other one please). Also, remember that you won’t be able to re-use your original ISRCs so all the streams generated until now will be lost.
