I think it's great!! I really love the Tridentine Mass/TLM/1962 Missal/Classical Roman Liturgy, now Extraordinary Form, as well as the Ordinary Form - both the same one Mass. I think it's wonderful how we can have two forms of the Roman Rite. Thank you Holy Father!

And I believe bringing back a wider use of the TLM will definitely help lessen abuses that have often taken place at the Ordinary form, eg changing the Eucharistic prayers from the official texts, extraordinary ministers when it is not an extraordinary situation (I've been to many Masses with less than 10 people, where there was still an extraordinary minister! :/ ), etc.
So much of the Church's sacred music has become extinct today in most parishes, at least mine I know. I think this will definitely be a huge step in restoring this, and bringing it to the ordinary form, as was the intention of the VII document on the Liturgy. I'm starting to discover more and more of it myself, and it is so unbelievably beautiful!

Up until recently, I was totally ignorant of pretty much all of this - all the beautiful hymns like Veni Creator, Salve Regina, Ave Maris Stella, O Gloriosa Virginum, Vexilla Regis, Jesu Dulcis, Adoremus te Christi (the one version I particularly love, often sung at Holy Communion, so beautiful!!

) Parce Domini, Attende Domini (often sung at Communion during Lent) and so many others!! the Te Deum - it makes me think of the Carmelite martyrs of Compiegne who sang that along with other Latin hymns on their way to the scaffold

- all the different parts of the Mass, the different forms of the Kyrie, Sanctus, etc - aah, I love the Alleluia verse for the Solemnity of the Assumption!! Alleluia, Assumpta est Maria!! There is so much incredibly beautiful Gregorian chant and other sacred music out there that is never heard anymore. On the very rare occasion that some of it is used at my parish, it is such an epiphany

WOW! amongst much of the other music!
Most of the music played at the ordinary form these days, at least at my parish, is so uncomparible. I remember my years in high school being really annoyed

at Mass, feeling it was just a superficial community gathering - and I didn't want to sing hymns that I really didn't like that weren't coming from the heart. In CCD we were not taught at all about the Real Presence and the sacredness of the Mass.
I had never been to a TLM up until a couple years ago. The first Latin Mass I ever attended was actually in the ordinary form at this beautiful little parish in Omaha, and it was great! As I began going more and more to the TLM in my area on Sundays, when I could/can, I realized so many things that I personally like much better, though of course I also love the Ordinary form - the same one Mass, where Jesus comes down on the altar - eg how it is often a more meditative atmosphere, not having to worry at all about trying to really concentrate on the Divine Mysteries taking place at Mass to prepare for Holy Communion, the most solemn moment of our lives, as St. Peter Julian Eymard says ( thread on his treatise on
Holy Communion) (often at my parish at the ordinary form I feel this way), receiving Holy Communion at the altar rail - soo beautiful!! I love how reverent it is, like right before Communion how they cover the rail with linens - it's as if you're receiving directly from the altar itself, and I feel so much more comfortable receiving this way - it is much easier to kneel down at the rail, and you don't have to worry about the possibility of Jesus falling to the floor (this has happen to me twice) Also, there is so much less of a risk distributing Holy Communion in this way, of people walking off with the Host, which seriously does happen (my mother has spotted people doing this on a number of occasions at my parish - and she stops them) or fragments of the Host being scattered. So often I find crumbs, and on a couple occasions, even whole Hosts on the floor at my parish.
