Maybe one day. I decided early on to leave them out for a few reasons. Firstly, there's a lot of confusion around them, with a lot of sites listing completely different things about them. Secondly, it would have resulted in me focusing almost exclusively on 70s and 80s heavy metal for a LONG time with little reward, delaying the true value of the site. Lastly, and perhaps most importantly to me, a lot of them have no artwork or it's next to impossible to find good images for them. As I hope you can tell, the visuals of Metal Academy are just as important to me as the content. I wanted this site to be the best looking metal site there is, and literally spend hours every day hunting down the very best images I can find for every release. I fear that adding singles would detract from the result.
