The two executive who lead Yahoo! Music have left the building. For good. According to ValleyWag.

Wall St. has been concerned for some time that Yahoo! is in too many businesses. The music download portion of the internet is populated by firms from Apple (AAPL) iTunes to RealNetworks (RNWK).

The departures may be random, or they could be a sign that Yahoo! will focus on its larger and more promising initiatives like search, YahooFinance, HotJobs, and Personals.
