No. But you can create a new Apple ID and iTunes account, pay another $24.99 for another Match account. However, the additional tracks will not be usable under the old account and vice-versa.
I have all my music in the library. I have a large number of tracks with iCloud status shown as "removed"
I achieved this by creating a second blank library - I signed into match and was able to view all tracks in iTunes Match.
I then deleted some tracks from this library - effectively deleting (hiding) tracks in the cloud.
When I went back into my original library, those tracks were shown as "removed". iTunes Match will now ignore those tracks. You can now add new tracks provided you keep matched and uploaded less than 25k.
This is a long process but eventually you can have all tracks in your library but with only selected tracks in the cloud.
I created a Library #2, did a Match, deleted a matched song from Library 2, went back to original Library #1 and the deleted song is now called an "error"
I can't play the "error" song now.
It does still show up in Library #1 (with an "error" cloud status.
Question: How do I get it back if I later want to hear it?
I tried to right click it; it briefly said "waiting" and then went back to "error"
