what do you mean without signing up? do you mean without paying? link is a website where you can download tracks or remixes of songs for free. if you make an account, you can also post tracks or make mixes yourself. most of the songs usually work on youtube videos, without getting removed for copyright purposes, but some don't. you can download these songs in mp3 formats to your computer. i hope this helps
