In general, Sonicbids is shifting away from paid listings altogether for a number of reasons. About 90% or more of our opportunities are free, and we're striving to make them all free.
Our members already pay a subscription for membership, so application fees really serve as a barrier to submissions. Because of this, we try to limit fees to highly visible or well-compensated gigs (like slots at Bonnaroo, SXSW, etc.).
If you create a free gig listing with Sonicbids, we market to our artist community for free. This gets your name and work out there to drum up interest and attract attention.
