Things never get dull for the country's lone satellite-radio provider. Shares of Sirius XM Radio (SIRI 0.98%) closed at $3.61, unchanged on the week. The media darling's meandering ways were trumped by Nasdaq's 1% uptick on the week.

There was more going on beyond the share-price gyrations, though. Liberty Media (FWONA) announced a conference presentation that may shed some light on its strategy with Sirius XM. Meanwhile, Amazon.com (AMZN -2.56%) is reportedly working on a streaming music service that could turn heads if it's bundled with its Amazon Prime service. 

Let's take a closer look.

Speaking up
Liberty Media announced that CEO Greg Maffei will present at the Morgan Stanley Technology, Media & Telecom Conference, on Tuesday. Naturally, the situation with Sirius XM is going to come up either in the presentation or the resulting Q&A. 

Retail investors generally aren't pleased with the terms of Liberty Media's proposed takeover, and it stands a pretty good shot of getting shot down unless Maffei either sweetens the terms or persuades more institutional investors that this is the best path to enrichment. 

You won't have to fight for an invite to the presentation. It will stream as a live webcast on Liberty Media's website. 

Pandora (P) will also present at the conference two days later, just around the time that it publishes its monthly performance metrics. After an initial setback in the weeks following the debut of iTunes Radio, Pandora's been growing again. 

New revenue stream for Jeff Bezos
It probably wouldn't be a surprise if Amazon jumped into the crowded streaming market, following either Spotify into giving listeners the ability to select tracks or going the ad-supported music discovery route that Pandora and iTunes Radio are championing. 

However, according to Re/code, Amazon may be rolling this out as part of its Amazon Prime platform. The leading online retailer conceded that it's exploring a price increase during its most recent earnings call, and this would be a great way to justify the increase. Then again, getting the stingy record labels to play along would be the real challenge.
