The deletion thing does not say you are unimportant. It says that the article did not show that you were important. There's a difference. It's the article that's being deleted, not you. Look at WP:BAND and WP:BIO - it's usually BAND for any musicians even if they always play solo or if they rap - if you can get through either of those as a pass, then look at WP:RS which is about the reliable independent sources needed to prove it. Then read WP:COI if you are the subject or are closely connected to the subject. Then contact one of us (at the bottom of our talkpage) and we'll advise you on the state of play. Not all people (or bands) get articles (but it seems like every schoolboy group and every rapper tries...). Some, like Bragod, are not in the charting/popular line, but can still have notability. (They didn't write that article, and no, I'm not one of them even though I do have a lyre and can play it.) I only found that you'd been to my userpage by accident - I looked at my watchlist (which I do on occasion). Talkpages flash up a yellow banner so we know there's a message.
