I want to move into music career. Any suggestions?

I agree with QuiGon. If you love music, start making it because you love it. Not because you want to make money. Because, unfortunately, it's a one-in-a-million chance that you'll ever even be noticed (let alone start earning enough to make a comfortable living), and if you're dead-set on making millions you're going to burn out and disappoint yourself. I wouldn't deviate away from your tastes and start using predesigned shit though, again, if you're just pumping out crap to make money you won't be happy.

I think you should make a spotify, youtube, etc. as well, to have a place to share all your music in one place. Make it a fun hobby of yours, and something you can go through later and feel proud of. By "music career" I have kind of assumed you've meant as an artist, but there's always the chance that if you want to go into the industry itself (like as a sound engineer or something else), you can use your profiles as a good portfolio too.

Best of luck!
