I haven't noticed the loud music so much, but "signature scent" is getting to be a problem for me too - it sets off my asthma. I've run into it at Westin, and I've run into it at Hilton Garden Inn. I've also been to a lot of HGIs without the "scent" so maybe Hilton is just experimenting and it's not a universal standard. I do hope this fad goes away quickly - I like to be able to breathe when I'm at a hotel.
