In this modern age, its smarter for bands to release singles instead of full albums or ep's, and physical media is as obsolete as ever before. Can bands that only release singles still be on this website? 

 

A good example is the band Sheer Cold - They are a very active deathcore band that's played dozens of shows and is starting to get a decent following. They have 5 singles, but no physical EP or album, or even a physical demo. 

Another good example is the band Mourning Anguish - they have 3 singles and are a great band, but no physical media

Neither of these bands are in the encyclopedia yet
