A different key would make your singer work harder & thus easily get more emotional & sound much better on Cocktail Hour. Not a bad tune, but it just doesn't really grab me, for some reason. Looking for that guitar.
Cruisin' Fusion is pleasant, but the overuse of the keys & their tone reminds me of a Bill Murray skit after awhile. Lounge lizardish.
I've been waiting for more guitar work to round out your sound. Ganja Mon doesn't have it either. It might be there, but I'm not hearing it at all in this mix. Vox get a bit off on this one & need to be redone, imo. Again, perhaps a higher key for your lead vocalist is called for. Not more than 1 or 1 1/2 steps, but I think it may help. Reggae needs a stronger bass, too, I think, than what you have here.
4th one, & I ask again, where's the guitar? This one needs it badly. It's screaming out for it. Nice upbeat stuff, as sans said, but it needs more than the keys, for me.
The drums seem mechanical. Are they real?
Bands that are totally keyboard-driven usually have more than 1 player. I could hear some nice tinkling ivories of real piano in there, some choppy guitar chording on the Ganja tune, a tasty lick with overdrive here or there, even a clarinet would help in some places, but the simple chording of electric piano gets old for me quick, if that's all there is to the arrangements. I think you need to use & emphasize your other band members far more than you are at present.
