This is a massive collection!
Can you add a feature matrix showing what each one provides?
Sound effects, Ambiance sounds, Music, Genre support, monthly cost, how many files, how long in business, number of subscribers/users/patrons, does it have a community, ease of use, etc.
I would love that!
After reviewing this, I feel that the forum list will work best for everyone, and I loose the advantages I had hoped to gain by listing them under resources.
Thanks for your help and work on this
