What services exactly does a label continue to provide, now that the internet has made it much easier for artists to self-promote? I presume that large portion of what the labels used to do can now be done very easily by the artists themselves.
There may be an opening for a tech startup here (maybe there's already one (or more) in this field) to take whatever the labels still need to do and undercut them on price and ease of acceptance (the labels are pretty picky about which artists they take). It seems to me that the labels have spurned a lot of the technological advances that have been made possible over the last decade or two in favor of clinging to an increasingly outdated business model in the hopes of squeezing a final dollar or two out of their musicians.
