As far as the comparison to bey first i think it's safe to say both are very talented women. Now as far as voices go yes bey voice is more powerful, but Aaliyah's was WAY more soulful, smooth abd sultry. What I don't understand is that GREAT singers like sade, billie holiday and a lot of iconic/legendary singers who don't necessarily have powerful voices has never been accused of being weak singers or not being able to sing but why aaliyah? Hating perhaps?! Aaliyah had a GREAT RANGE thats still UNDERRATED like how she could do a try again, then hit u with a the one i gave my heart to, then a at your best, then a death of a playa ALL "DIFFERENT" RANGES and lastly put them ALL TOGETHER in ONE SONG I care 4 u, that song's vocal arrangement and delivery is SICK. As far as overall talent goes they BOTH had things they were better at vocally bey was more powerful and aaliyah was more soulful & versatile. Dance wise bey is more big movements while aaliyah was more smooth, refined and also much more versatile. Acting wise Aaliyah was FAR SUPERIOR and again more versatile. ALL her roles were DIFERRENT queen from romeo, romeo from matrix, matrix from sparkle, sparkle from honey, honey from some kind of blue, all were COMPLETELY DIFFERENT CHARACTERS (RANGE), while bey seems to play the SAME characters over and over again and still don't do them well beside doing alright in dreamgirls and ok in cadillac records. Last but certainly not least musically again they both have something different bey is OVERALL MORE COMMERCIALLY SUCCESSFUL 18 years+ but hey Aaliyah wasn't no slacker either 7 year career with a 5 YEAR BREAK and atill at 22 manage to deliver 2 MULTIPLATINUM ALBUMS "AS A TEEN" and a GOLD ALBUM in 4 WEEKS (b4 she died) which WERE ALL COMMERCIALLY SUCCESSFUL DOMESTICALLY AND INTERNATIONALLY BUT ALSO "ALL" CRTICALLY FAVORED WITH HIGH PRAISE. And I'm still waiting on bey in her 30s 18+ years in the game to deliver a GROUNDBREAKING/GAME-CHANGING/DIFFERENT FROM LITERALLY EVERYBODY ELSE ALBUM like Aaliyah WAS ABLE to do at 16/17 (OIAM) and follow up with an album even more GROUNDBREAKING/FUTURISTIC/TIMELESS/EXPERIMENTAL AND EXTREMELY RISKY/COMPLETELY DIFFERENT FROM ALL HER CONTEMPORARIES ALBUM like Aaliyah was able to do AGAIN AT 22 and still be COMMERCIALLY AND CRTICALLY SUCCESSFUL. So all in all who knows what Aaliyah's career would be if she was still here what can't be said no matter HOW HARD YAL TRY was that the girl was MULTI-TALENTED, INNOVATIVE abd did the damn thing and then some while she was here.
