Just a heads up that any songs from your library that are "matched" after you subscribe are locked with DRM. I'm still under my iTunes Match subscription which would let you re-download matched songs with no DRM at 256kbps quality. After subscribing to my Apple Music free trial, I added some new music (ripped CD locally from my computer) and all the tracks were listed as "Matched". I tested re-downloading them and they all end up as m4p's (protected music files). Files "matched" before subscribing still download with no DRM. I'm hoping that if I were to cancel at some point and stick with the cheaper iTunes Match functionality, I'll still be able to grab the all matched files unprotected at that point if needed.
