I see this has been mentioned before, but not for a few years now and I thought there may be new people here who'd appreciate it. Every 8 weeks Mercedes release a free mixtape (well, a zip file containing MP3s) of what is usually some really rather good music by new artists. It's a refreshing break from the mainstream that's rammed down our lugholes and a reminder that there's much more quality music out there. The compilations are only available from the official Mercedes site for a limited time along with some funky accompanying videos, but thanks to the magic of the internets, the complete catalogue of compilations is available from here. There's also a Facebook Group, if you're so inclined.
