Oh yeah, Ja Rule isnt that good. "Venni, Vetti, Vecci" was a solid album, but he went from "I'm killin everyone" on his first album to "I love to cry" on his second. Havent gotten a chance to cop the new one, but I hope its not all about crying and stuff, but I'd imagine it probably is. "Always on Time" is a good song, but I'm sure they'll overplay in on MTV/the radio.
Stick with Dr. Dre, N.W.A., Eazy E, Tech N9ne, Kid Rock (he's got 7 albums out, pop kiddies), and Wu-Tang Clan and you'll never go wrong, rap-wise.
