SoundCloud recently announced a shift to its subscription options. After initially making SoundCloud Go its full, on-demand option, that service is now a mid-tier level costing $4.99 a month. The $9.99-a-month tier is now called SoundCloud Go+. The Go option will have a smaller collection of available tracks, while Go+ offers the entire SoundCloud library.
