Can't redownload songs from iTunes store back into library
I moved my iTunes library from my Windows laptop to my Macbook..The only songs that I can't seem to find (have exclamation points next to them) are all ones I have purchased in the last month or so. Those songs show up in the purchased section in the iTunes store, however they don't have an iCloud icon next to it so I have no clue how to redownload them.
When I try to "get info" on the songs in my music library, it says its in some .trash file that I am not finding.
MacBook Air, OS X Yosemite (10.10.2)
