A type beat is an original instrumental written in the style of a specific artist or regional scene, sold or given away so that independent rappers can record over a sound they already recognize. Kooba II's "Dirty Diana" is a Detroit x YN Jay type beat: a chopped sample, a swung low-end bounce and drums that sit in one pocket from start to finish. The untagged file is available for purchase at the BeatStars listing for "Dirty Diana", and the tagged stream version is free for non-profit use.

What a Detroit type beat actually sounds like

A Detroit type beat is defined less by tempo than by swing, sample treatment and space. The scene around YN Jay, Rio Da Yung Og, Babyface Ray and Baby Smoove built its identity on looped soul and gospel chops, pitch-shifted vocals, and drums that push slightly ahead of the grid instead of sitting square on it. Producers working in this lane typically keep the kick pattern sparse, let the hi-hats carry the motion, and leave room in the midrange for a rapper's ad-libs.

"Dirty Diana" follows that formula closely. The sample is chopped rather than simply looped, which gives the loop a stutter that keeps repeating without sounding static, and the low end stays glued to the kick so the bounce reads clearly on phone speakers as well as in a car. That combination is what listeners describe as the Detroit bounce: a groove that feels relaxed at the top and heavy at the bottom at the same time.

How to license "Dirty Diana" correctly

The free download and the paid lease are two different licenses, and mixing them up is the most common way independent artists lose a release. Kooba II's terms are explicit, so treat them as a checklist before you upload anything.

1. Free use covers YouTube videos and SoundCloud uploads without monetization. Streaming services are excluded entirely.
2. Spotify, Deezer, Tidal, iTunes and comparable platforms require a purchased lease.
3. Content ID registration is not permitted without an exclusive license, so do not whitelist the beat in a distributor's content system on a free or lease tier.
4. Credit is mandatory and must read "Prod. Kooba" in the title or description.
5. The untagged file and the current buy-2-get-1-free bundle are handled through the producer's BeatStars store.

If you plan to monetize, buy the lease first and keep the receipt; distributors increasingly ask for proof of licensing when a track starts earning.

Writing to a sample-based beat without fighting the chop

A type beat with a vocal or soul chop already occupies the frequency range a rapper instinctively reaches for, so the writing has to work around the sample rather than on top of it. Three practical adjustments make the process faster.

• Write in the gaps. The chopped loop in "Dirty Diana" leaves short pockets between phrases; placing a bar-ending punchline there makes the vocal sound produced rather than pasted on.
• Keep the flow conversational. Detroit and Flint rappers rarely crowd every beat with sixteenth notes; the delivery is closer to speech, with ad-libs filling the rests.
• Record ad-libs in a separate pass. Doubling the main vocal and stacking a few ad-libs on the empty beats gives the mix the width the sparse arrangement expects.

If you are new to the scene, study how YN Jay and Rio Da Yung Og treat a loop: they often repeat one cadence for four bars before switching, which lets the sample carry the hook.

Common questions producers and rappers ask about free type beats

The discussion around free instrumentals tends to repeat the same three concerns, and each has a straightforward answer. First, a free type beat is not the same as a royalty-free beat: the producer keeps ownership and grants limited use, which is why streaming platforms are usually excluded. Second, a lease is not a transfer of ownership; it is a time-limited, non-exclusive right to distribute a set number of units, and the producer can still sell the same beat to other artists. Third, crediting the producer is not a courtesy but a license condition, and omitting "Prod. Kooba" can trigger a claim even when the beat itself was downloaded legally.

A fourth recurring question is whether one sample can support many beats. It can: the same source record can be chopped, filtered and re-pitched into dozens of different instrumentals, which is why sample-based scenes produce so many variations on a similar palette. What separates them is the drum programming and the arrangement, not the source material.

Where to find more from the producer

Kooba II publishes free Detroit, Flint and YN Jay type beats alongside the paid catalog, and the fastest way to follow new drops is through the producer's own channels. The Instagram account at https://www.instagram.com/prodkooba carries previews and release announcements, while the full beat store at https://www.beatstars.com/prodkooba lists every instrumental with its license options and bundle pricing. Both links are worth checking before you start a project, because the buy-2-get-1-free offer applies across the store rather than to a single beat.

Conclusion

"Dirty Diana" is a clean example of the Detroit type beat format: a chopped sample, a swung bounce and drums that stay in the pocket the whole way through. Kooba II gives it away for non-profit use and sells the untagged file through BeatStars, so the path from listening to releasing is short as long as the license terms are respected. Credit the producer as "Prod. Kooba," buy a lease before you hit streaming services, and keep Content ID off the beat unless you hold an exclusive. To grab the untagged instrumental and the current bundle, head to the "Dirty Diana" purchase page on BeatStars.
