I am unaware of any others that are independent and publicly traded such as BUNM. Of course some of the big boys have music players integrated into their companies. Here is a blog that talks about some of the goings on of the big music companies. Seems they are interested in putting music videos on social networking music websites and BUNM has Hypstertv.....So hopefully they are eyeballing HYPSTER!!! Come on Google....Google & Hypster...has a nice ring to it, don't you think!!!! LOL
