These are the songs I've felt like bringing up on the main page from time to time, with title and artist and also a link that hopefully isn't broken. Essentially if a song gets stuck in my head I'll drop it here. I'm not a fan of whatever YouTube is doing generally, but as the Internet's dumping grounds, you can find a lot of things there, such as songs, so the listen links are likely YouTube ones. The links might also be blocked by region or other arbitrary factors because companies/governments are stupid like that.
The "listen" links will open in a new window or tab, depending on your browser. There may be possible restrictions, but I try to find a generally accessible link as far as I can tell. If they don't work, then resort to other means. You can also hover over some songs to see additional thoughts.
