US-based recording company Hitmatic Records has locked down FM radio with the Ackee Seed rhythm featuring several dancehall heavyweights and a nice mix of younger acts.

The rhythm is a bouncy, typical, dancehall groove, but what makes it special are the wicked, ice-pick-sharp synthesiser beats that raise the tempo to a new level of lyricism each time they chip in. This is the factor that brings out the best in the artistes.

Flexx is a solid deejay with a nice turn of phrase, and he delivers the goods when he combines with the billboard-charting Ms Ting on Gimme Wah Mi Want. The air is charged with sexual chemistry when Flexx and Ms Ting begin their sexy interplay, using delicious metaphors and racy imagery that would make even a ghetto barmaid blush.

Beenie Man is at his hitmaking best with Thunda Roll, a vibesy romp where Beenie swears he will never change his womanising ways. Beenie Man has an uncanny knack for coming up with catchy singalong hooks where he swears: "thunda roll and bruk mi neck and buss mi head, mi woulda rather dead before a bwoy coulda touch mi like how him touch him head".

Capleton is one of those rare dancehall figures whose voice gains force and resonance as he grows older. Capleton wows the listener on Fire Light Dem, bringing fire and energy to his verses and great lyricism to the chorus as he deejays: dem always blame the music and neva blame the media/Demnever blame the alcohol, dem always blame the weed-ya/mi never hear dem put nuh blame pon the false leada".

Sizzla shines on That's What You're Looking For and he waxes lyrically as he serenades a girl, promising that he has the goodies that she needs and has been looking for. Pinchers goes hardcore on Needle One as he describes a passionate night of lovemaking while Merciless brings his deep gravelly voice to the boudoir with Bed A Rattle. He deejays: "Di bed a rattle/gal inna mi tabernacle/her body ah get hackle/and her foot dem shackle/gal fi get slide tackle". It's all a bit kinky, but Merciless shows that he can still kick rhymes with the best of them.

Spice shows why she is the heir apparent to Lady Saw with the hard-hitting Gyal A Chatwhere she lists out her numerous achievements while taunting her matey who "no more than mi/she nuh look good like mi/gal yu nuh shape like mi".

Lisa Hyper boasts that "mi bad inna dance and bad inna bed" on Giddy Up, and shows she knows a bit of astrology with rhymes that reference the planets of Mercury and Pluto.

Lady Saw goes raw on Truth Be Told where she lists out the merits of her, ahem, assets, bragging that she knows how to swing on the pole, and how she has the best body part that rhymes with pole. If you didn't know it before, Marion Hall has been put on mute, Lady Saw is back and she means business.

Other standout songs include Mad Cobra's Hairdresser Nuh Like Her, and the fiery Face lays down a challenge with Talk. Newcomer Jevari shows just how talented he is and that he is a voice for the future with the pop-influenced Just As I Am, while Derrick Parker brings humour with Mix Up Time. Newcomer Shana S also does well with Tell a Gal Fi Back Up where she shows her 'bad-gyal' credentials.

The rhythm project is available on iTunes, Amazon.com, Emusic and other downloadable sites.
