Is There a Music Tech Bubble? 

Spotify and competing subscription service Deezer, which just announced $109 million in new funding, are just two of thousands of companies to take advantage of readily available capital. Last year, global funding for venture-backed companies grew to $128.5 billion (from $89.4 billion in 2014) and more than doubled the $50.2 billion spent in 2013. In the United States, total funding jumped to $72.4 billion from $57.4 billion.
