5 reasons Tesla's music-streaming service is the best idea Elon Musk has had this year

Last month, $4 revealed that $4 for its vehicles (and, presumably, other environments, such as smartphones).

Tesla has a lot going on now, from the initial rollout of the $35,000 Model 3 mass-market to CEO Elon Musk's apparent plans to support a Hyperloop route between New York and Washington, DC. But the streaming service is particularly notable, mainly because it's so plausible.

The service is unnamed, but we're going to suggest "Tesla Tunes" over "Tesla Music." Regardless of what it ends up being called - and whether Musk, evidently a fan of classic rap and hip-hop as well as certain $4, hosts his own show - it is one of the best ideas the company has had in a while.

The streaming-service concept follows on the heels of some questionable ideas, chief among them the 2016 acquisition of SolarCity, which loaded up Tesla's balance sheet with debt and created a transportation-and-energy conglomerate that is now difficult to accurately value.

Here's a breakdown of the brilliance of Tesla Tunes:
