I track all the latest spotify releases, in salsa, bachata, merengue and cumbia, and manually select the most noteworthy tracks. These go into the following playlist, which I maintain for my own professional use. I have decided to make it public though, and if you want to keep track of the latest releases, you are welcome to subscribe.
The playlist is regularly updated. Newest tracks are at the top, oldest tracks at the bottom. Anything older than approximately 3 months gets trimmed down.
