XM and Sirius Radio are pulling a few surprise moves in the latter half of May, offering out elements of Sirius’ top (and usually exclusive) programming in an effort to attract more subscribers to the Best of Sirius package.

From May 18th through until the 25th XM subscribers will be able to enjoy a taste of what Sirius has to offer. Broadcasts will include channels and shows from Howard Stern, Bubba the Love Sponge and more.

The decision to essentially “loan out” key programming is another go by Sirius to entice XM listeners through the kind of trial offers that have worked best in the company’s past.
