If you increase your iCloud storage capacity can you increase the number of songs that exceed the 25,000 limit on the iMatch. If it does not apply specifically how can I increase this rather constrained limit?

The whole business of cloud storage is unclear to me. They say that you have 5G of memory free upgrade to 15 for twenty-five dollars and that this is unrelated to music and video memory. I get this, but I have purchased iCloud Match for $25 but I've quickly maxed out the 25,000 song limit. How can I increase this limit. It is at this point I am unclear about the $25 for 15G additional storage... can this be used to increase iTunes/iCloudmusic storage to increase the music Storage? One would think that apple would make these distinctions clearer. Can anyone carify? Thanks!
