I see why you say that, but to me, this is the interesting and most debatable point in the thread - whether it is appropriate, inappropriate, sad, expected, enthusiastically received, decried, etc, etc. for an attractive person to use their looks to their professional advantage.
The moral position would probably lean towards negative, especially when the person in question is young like Tal is. Empirically, though, we can see many examples of young, attractive people leveraging their appearances in addition to their undeniable talent to make the most of their opportunity.
Two examples - Danica Patrick, an Indy car driver, states that she understands and encourages the attention she gets because of her appearance, so long as it results in more exposure for her sport overall.
Last night I watched an MTV-HD presentation of a live unplugged concert that Alicia Keys did. She also is a relatively young woman who is absolutely burning up with talent, who is not at all hard on the eyes. She looked great in the concert, and when the guy from Maroon 5 did a guest appearance the first thing he mentioned was how great she looked (and sounded). It's never been my opinion that she avoids being perceived as beautiful, nor presenting herself thus.
I'm not necessarily taking a position, just providing a few data points.
I don't think the comparison to Alicia Keys, in particular, is valid. Alicia, who I really admire, is a singer, a person who is out front. Looking cute and sexy is a huge part of being a pop star. I remember the first time I ever saw Alicia Keys was on the cover of a magazine reclining in tight jeans with snap undone and the zipper halfway down. I had never heard her sing a note, but that photo sure got my attention!
Tal, however, is always in jeans and t-shirts or flannel. I can't speak for anyone else, but that look says to me, "I'm a player," not "I'm sexy."

I think it is about time somebody brings our attention back around to actually PLAYING the bass. Too many of us are out there getting wrapped up on how BIG our basses are, and how fast we can slap the *%#$ out of it. Leave it to a talented young lady to get us all talking again.
