We currently use a template within "posts" in wordpress to create individual URL's for each track that we write in our recording studio.
This has been a very efficient way of tracking versions and sharing music.
Above is an example.
There are currently 3 things that need doing
1 - The existing posts do not view correctly inside chrome (you can test it yourself) - this needs to be fixed.
2- We would like to upgrade the media player so that we can have a scrub function (fast forward / rewind)
3 - We would like to have a new template for posts so that we can have multiple mp3's housed on each page each with individual download links.
