An Osamason type beat is a instrumental built to match the sparse, distorted, high-energy sound Osamason and the wider flex music scene rap over, and "ITS A PARTY" by onezen is a direct example: 152 BPM, Ab major, produced by onezen and aen, free for non-profit use and licensable for streaming through the purchase and free download page. The track sits in the same lane as Nettspend, psykotic and wegonebeok type beats, which is exactly why those tags are attached to it.

What defines an Osamason type beat

An Osamason type beat is defined less by a single drum pattern than by contrast: thin, piercing melodic loops against drums that hit hard and leave space. Producers chasing this sound usually work in the 145–160 BPM range, keep the low end simple, and let one distorted synth or bell carry the whole loop. "ITS A PARTY" follows that logic at 152 BPM in Ab major, a key that suits bright, slightly detuned leads without pushing the mix into harshness. The result is a beat that reads as "hard" first and melodic second, which is the balance most flex music instrumentals aim for.

The specs behind "ITS A PARTY"

The concrete numbers make the beat easy to place in a session before you even press play. Here is what the release sheet states:

1. Tempo: 152 BPM — fast enough for double-time flows, slow enough for half-time hooks.
2. Key: Ab major — bright tonal center, useful for auto-tuned melodic runs.
3. Producers: onezen and aen, credited together on the beat.
4. Format: free download plus paid license options through BeatStars.
5. Offer: buy two licenses, get one free when three identical licenses are added to the cart.

For artists who write to reference tracks, 152 BPM means a 16-bar verse lands in roughly 25 seconds at a straight count, so a standard three-verse structure fits comfortably under three minutes before a hook repeats.

Free for non-profit, paid for streaming

The licensing terms are the part most artists get wrong, and they are stated plainly: the beat is free for non-profit use only. That covers practice recordings, unreleased demos and non-monetized uploads, but it does not cover distribution on DSPs such as Spotify, Apple Music or YouTube Music. If a song using this beat goes to streaming platforms, or into any monetized project including YouTube videos with ads, a license must be purchased from the producer's site. In practice that means the free download is a writing tool, not a release tool — clear the license before you schedule a drop.

How to use the beat in a session

Start with the tempo and key, then build the vocal around the space the beat leaves. A practical workflow:

1. Download the beat from https://bsta.rs/PP1iPD and import it at 152 BPM, confirming the DAW grid lines up with the loop.
2. Write the hook first — the Ab major tonality favors sung or half-sung melodies over the drop.
3. Keep verses rhythmically dense but leave the ad-lib pockets open; flex music instrumentals are mixed to let short vocal chops cut through.
4. Track a reference mix, then decide whether the release is non-profit or commercial before spending studio time.
5. If commercial, buy the license and keep the receipt — platforms and Content ID disputes ask for it.

Where this beat fits in the flex music landscape

The tag list around "ITS A PARTY" maps the sub-scenes it can serve: flex music, hard Osamason, psykotic, ok and wegonebeok type beats. Those names describe overlapping audiences rather than separate genres — artists like Osamason and Nettspend share producers, tempo ranges and a preference for abrasive, compressed loops. A 152 BPM Ab major beat can therefore sit under a distorted rage-style hook or a more restrained, almost melodic verse without sounding out of place. Producers searching for a hard Osamason type beat free for profit should note the distinction: free for profit is not the same as free for streaming, and this release only grants the latter under a paid license.

Final take

"ITS A PARTY" is a clean, well-documented entry in the Osamason type beat catalog: 152 BPM, Ab major, two credited producers and licensing terms written out instead of implied. The buy-two-get-one-free offer makes it practical for artists who want several beats from the same catalog under one clearance. Channel onezen is the source of this breakdown, and the BeatStars page at https://bsta.rs/PP1iPD is where the download and the license both live — start there before you record.
