When I arrived on the ez-tracks.com website I will say, there was quite a bit going on visually and aurally. The site had a pretty busy layout, which didn't bother me as much as the music that automatically began playing as I arrived on the site. Even though, I myself am a musician, I dislike arriving on a web page where music automatically begins playing. I think the site visitor should have the option to turn any music on your site on or off (if that function exists on the ez-tracks.com site I apologize for bringing it up, but I couldn't find it).
I am not an avid ez-tracks.com user, but I did find it's business model beneficial for music listeners. Plus, the benefit for indie musicians I think comes from ez-tracks.com's Up and Coming Artists section. This is an area of the website to find indie music. There's even an opportunity to add your band to EZ-Tracks, which may be a helpful for indie musicians to be discovered by new fans (over 3000 Facebooks Fans have "Liked" EZ-Tracks, according to their site).
As stated on the ez-tracks.com website, here's the value they offer and how they offer it:
