I used the site for about 3 years and have pretty good perspective. Obviously, I'm not rating it well for some strong reasons, so I'll start with those. First - many better music distribution options (CD Baby, Distrokid, etc) that have a 1 time setup fee and then perpetually collect royalties. Reverbnation charges more, charges yearly, and takes a bigger cut. And - if you don't use reverberation for distribution, you have NO WAY of collecting royalties for plays on their site...no matter how many. Second - the whole "charts" is a sham, and its a way for them to sell you promotion for plays that rank your chart. Third - you are primarily marketing to other musicians and bands, which is just kinda flawed entirely. Fourth - the yearly fees for use are not in line with other options. Fifth - opportunities - regardless of having many songs "curated" by the site, I've only been sent through to maybe a couple "opportunities" (which many of those opportunities are available free with just a little searching). There are SOME positives. Their AD sets seem to actually publish to decent sites, but I don't think are as cost effective as other marketing options. The ADs seem to be "rigged" to where they throttle the amount of ADs displaying your songs to achieve a certain amount of exposure and pull back AD count if you getting too many plays, I've seen this. They seem to allow 10%-20% views to plays ratios, but if you start exceeding that (and I have), they throttle back the amount of ads. It's a strange thing. So for 100 ad views, you can expect between 5-20 song plays, regardless of your weekly "budget." So I think there are other better marketing options too. Hope this is helpful
