I have to agree with Gold here -- I think it would be better to merge votes into a more general request for improvements to the sound offerings within Roll20. This is one of the most distinct differences, IMO, between roll20 and other VTTs.
Also, I've got a bit of a love/hate relationship going on with TableTop Audio, which I've been listening to for weeks (and I'm listening to it now).
I LOVE the look and feel of the site, it's extremely well done. But, I don't know if it's terribly scalable, if he keeps adding tracks, to be looking over a large matrix of selections rather than making it searchable such as can be done at
http://incompetech.com.
Also, I love the audio quality as well, but the different sounds tracks aren't really all the dissimilar in their
feel. The owner of the site likes soft, brooding sounds regardless of setting it seems. I'm listening to it now and there is nothing in here that really is peppy, happy, or fast-paced if you ever wanted to create that kind of mood.
