I noticed one can search for an artist, but what if I don't know that artists name? I would be a good idea to have in that search drop down to search by talent, IE, if I'm looking for someone to collab on a piece and I'm looking for a guitarist, I would like to be able to search for 'Guitarist' by talent in the search box, then I can 'audition' some of his/her music, and choose if this person has the right sound for my project. Also the artists profile could have a section where they enter their talents either as a drop down selection or as tags, which can be used by the search engine.
In due course, we'll have something like this. It's just me writing the code for the site, and I can only do it when I have free time. But yes, I've thought about this exact issue, and it's something I'd like to do.
