In case you missed any of these catchy tunes last week, it's not too late to boogie down. Grab your headphones, CD player, iPod, speakers, guitar, cowbell, whatever you need -- it's time for the M&A Mix Tape.

"Welcome to the Black Parade" by My Chemical Romance, XM, and Sirius
I figured it'd be the big elephant in the room if I didn't lead off this review of last week's deals with the proposed merger of XM Satellite Radio (NASDAQ:XMSR) and Sirius Satellite Radio (NASDAQ:SIRI). The terms of the deal qualify it as an actual merger -- investors on both sides will hold roughly 50% of the outstanding stock after the deal. If it happens. Mel Karmazin, Sirius' current CEO, will be the CEO of the combined company, and Gary Parsons, XM's chairman, would be the chairman. If it happens. Wall Street is projecting $3 billion-$7 billion in cost savings from the merger. If it happens.

Did I mention that there's a lot of speculation that the deal won't happen? The FTC still has to give its stamp of approval, and anticompetitive concerns could provide it with reason enough to kill the deal. You only have to talk to DirectTV or EchoStar to see how that feels.

Morgan Stanley (NYSE:MS) is working the deal on Sirius' side, while JPMorgan (NYSE:JPM) is advising XM.

"Keep Holding On" by Avril Lavigne, Warner Music, and EMI
Warner Music Group (NYSE:WMG) didn't want to let go. After being rebuffed last year in its efforts to combine with EMI Group (home of artists like The Rolling Stones, Gorillaz, and Korn), Warner issued a press release last Tuesday admitting that the two have been in talks since late January.

This time around, though, Warner has convinced the Independent Music Publishers and Labels Association (IMPALA) to get behind the idea. In order to win this approval, Warner said that it would support IMPALA on its Merlin digital rights program, divest certain music assets, and make "other behavior commitments which have the aim of benefiting the recorded music market as a whole." And who says love can't make you change? I think it's sweet.

But no love story is complete without plenty of adversity. Along with the regulatory hurdles that already stymied the two once before, the New York Post reported last week that Apollo Management and Permira may be sniffing around EMI again, too. There have been no formal offers from Warner or the PE groups yet, but 2007 is still young, and Warner may be eager to work on something that'll keep them from thinking about its recent earnings release.

"Mercedes Benz" by Janis Joplin and DaimlerChrysler
"Oh Lord, won't you buy me a ..." Oh, wait, that's not what's up for sale. Did anyone ever sing a song about wanting a car from Chrysler really badly? The automaker's Town & Country just doesn't quite have the same appeal, I guess.

In any case, JPMorgan is preparing to send around a book to potential bidders for DaimlerChrysler's (NYSE:DCX) Chrysler business, which Daimler-Benz bought back in 1998 for $36 billion. An analyst at Morgan Stanley suspects that the company could end up being unloaded for somewhere in the $6.5 billion range -- a pretty lousy return on the investment, but likely a good outcome in the eyes of many Germans eager to cleanse the Stuttgart-based company of the whole debacle.

Renault and Nissan, both run by Carlos Ghosn, have already expressed that they don't have any interest in the deal, but GM (NYSE:GM), a few private equity and hedge funds including Cerberus, and other foreign auto makers looking for a U.S. foothold have been floated as potential bidders. Comments from Chrysler late in the week suggest that the company is still trying to fix the struggling unit while it explores an outright sale, and a decision on which direction it'll take may not come for another few months.

In the meantime, in hopes of the sale, I can almost hear the collective German sigh of und tschuess (good riddance!).

Liner notes
In other M&A news, aggregate supplier Vulcan Materials (NYSE:VMC) announced that it will buy out Florida Rock (NYSE:FRK) for $4.6 billion in cash and stock. It's a tough draw for Florida Rock investors who hopped on the stock in the middle of last year, when it was flirting with highs in the mid-$60s. The deal came at a 43% premium to Florida Rock's trading price at the time of announcement, but the stock was down 27% from its 2006 highs. Goldman (NYSE:GS) worked on the deal from the Vulcan side, and Lazard (NYSE:LAZ) was in Florida Rock's corner.

On Thursday, Getty Images (NYSE:GYI) announced the acquisition of MediaVast, the parent of WireImage, a provider of entertainment and event-focused images. More interesting to investors, though, seemed to be the confirmation by Jupitermedia (NASDAQ:JUPM) that the company is in talks with Getty as well. Unfortunately for speculators who rushed in when rumors started Wednesday, Jupiter said in its press release that the price under consideration is $9.60 per share, not the rumored $11.

And finally, Whole Foods (NASDAQ:WFMI) made a tender offer for Wild Oats Markets (NASDAQ:OATS). The $18.50 per share Whole Foods is offering, along with Wild Oats' net debt, values the transaction at $671 million and would make it the largest acquisition Whole Foods has made to date. Though Wild Oats may be an obvious business fit for Whole Foods, the company hasn't exactly been tearing up the world, and it could be a bumpy ride for Whole Foods to get it up to speed. RBC is advising Whole Foods on the transaction, and Citigroup (NYSE:C) is working with Wild Oats. The debt offering that Whole Foods is making in conjunction with the acquisition will be co-managed by RBC and JPMorgan.
