There ought to be a more accessible way to IM through the application, that would make spotify a more social platform for its user base. It would also make music sharing more sociable akin to soundcloud but with a better interface. The current message/sharing activity is too clunky and consequently a nuisance to use. Additionally a default playlist for songs sent to you would be a good idea as it makes it easy to collate them.
