would be an abilty to see how long you've listened to various artists for, i.e. the amount of minutes you've spent listening to them
its ok for songs which are generally 3-5 minutes long, but a lot of musicians are denied from getting near the top of any list because of the lenght of their songs. godspeed, fela kuti, acid mothers temple, as well as much jazz (particularly fusion), ambient, prog and krautrock are all a bit underrepresented.
not that it matters particularly , but id just be interested to see what ive spent more time listening to.
if its not possible with the scrobbling software they use then let me know. otherwise i might make a request
