My neighbors who are cultural novus Ordo , I would give out this guys cds instead of the vulgar rap garbage they listen too.  

It's not bad, I guess ... though it's not TOP quality, as far as rap goes, IMO.  I haven't listened to very much, of course, but there are some other "Christian" rappers who are better, IMO.  He doesn't seem to have too much material on his channel, so perhaps it takes more practice.

I think the question is whether rapping is compatible with Traditional Catholicism.  Obviously it's not Classical music, and there are negative associations with rap culture.

I'm not sure.  I don't think there's too much harm in it as long as he keeps its clean.  It's almost more like poetry with a strong beat.  Poetry inherently has to have some kind of rhythm to it, and the raps has a strange sense of blending the rhythm of the music and the rhythm / cadence of the words.

I look at his latest, from about 3 weeks ago, and the message is about Saturday afternoon Confessions being too short, so by "Traditional" Catholic, I'm sensing more Motarian.  He did cite St. Leonard regarding the fewness of the saved.

This is where some people would express a problem, that the beat riles up the passions and makes it automatically "not Catholic". 

Agreed.
No music with drums allowed in my house.

"Praise him with timbrel and choir: praise him with strings and organs."
[Psalms 150:4]

The timbrel or tabret was the principal percussion instrument of the ancient Israelites. It resembled either a frame drum or a modern tambourine.

And what about drums used in the percussion section of classical arrangements? Are those allowed? 

This is where some people would express a problem, that the beat riles up the passions and makes it automatically "not Catholic". I've had someone question the beat of a bluegrass song when the lyrical content was wholly Christian.

A little tangent: I don't agree with there being a "Catholic" type of music, apart from Chant (for obvious reasons), because all music ultimately comes from the Good, Almighty God. Relegating one's musical tastes to just classical is ironic considering that a lot of classical composers are either Masons, heretics, and infidels; so saying that is the only alternative option for Catholics is silly. Music is ultimately subjective, a certain type of music or beat may effect one person's passions more strongly than another's. And it can also serve a purpose to elevate one to contemplation of the Good, sometimes among otherwise non-Catholic artists.

Is there bad music? Certainly. But that has to do with the corruption of musical beauty itself. A lot of mainstream pop music is hardly music in the sense that it follows a specific formula as it is intended to be a product, not something that elevates the soul. Yet you can't necessarily condemn the type of music as there are artists in each genre that are capable of such an elevation, even if rare. So even if I don't like rap music, I can't sit here and say this is bad or not Catholic.

I don't think the beauty of music is subjective. There is an order to music, and this is something that Catholic thinkers have maintained pretty much forever. Rhythm, though an essential feature of all music, has its proper place USUALLY in the background. And rhythm does excite the passions
.
That isn't the whole story though. We are passionate creatures by design rather than by fault. The trick is ensuring that the right passions are excited at the right time, toward the right thing, and in the right amount. Example: a military march (typically percussion forward). A military march isn't 'disordered' music, it's music for a very specific purpose and it serves that purpose well (you want your soldiers alert and energetic as they approach the enemy line).
.
Not sure how this all applies to the song in question. I listened to it. I listen to hip hop occasionally anyways. As a genre, hip hop is analogous to punk rock. The best hip hop is somewhat agitated, appreciably poetical and cleverly verbose, and usually has its eye on some political, social, or philosophical muse. The problem is that it is hard to transmit an appreciation for goodness through that format (it's much easier to issue criticism through that format, though). The artist tries, but I'm not sure he succeeds. I was turned off by his proud request to be crucified like St Peter. I think he means well, but I think he missed the point. 
.
Like punk rock, I think hip hop should restrain itself to topics worth being angry over. There's nothing he's really talking about that's worth being angry over. 

This is where some people would express a problem, that the beat riles up the passions and makes it automatically "not Catholic". I've had someone question the beat of a bluegrass song when the lyrical content was wholly Christian.

It can, and I wouldn't recommend listening to it full time, but I don't think an occasional listen here or there does any harm.

As for the rap beat, my general impression is that it can incite more the passion of "irascibility" rather than concupiscence, and there's a fair bit of pre-modern music that's meant to, say, inspire men to fight valiantly in battle, and, yes, they relied heavily on drumbeats.  Some of those were posted in a thread here.  In any case, I don't think that rap poses any issue with concupiscence (provided that it's not accompanied by impure lyrics or an impure images / videos) ... in moderation.  Given its martial rhythms, it may even actually serve a purpose to offset a bit the "soyboy" culture.  If a young man is more along the lines of soyboy, then lighting a bit of a martial attitude might inspire a bit of toughness.  I suspect it's why RAP got so big in Black gang culture, since it does tend to incite a more martial spirit.  Most of the impurity tends to come from pop music (including Black pop music) ... if of course the rap isn't accompanied by impure images.
