SiriusXMU
radio station

SiriusXMU (formerly XMU, and known as Sirius U on Sirius Canada, although Sirius receivers list it as Sirius XM U) is an indie pop, indie rock, unsigned artist music channel on XM Satellite Radio channel 35 (previously 43).
On November 12, 2008, it was added to Sirius 26 (replacing the Left of Center channel), moving to Sirius 35 on May 4, 2011, and Dish Network channel 6026. Until February 9, 2010, it was on DirecTV channel 831. The XM DJs were replaced with Sirius DJs, and acquired its current name, even though the channel is still listed as X043-FM by Mediabase. Sirius XM describes the channel as "North America's Indie Rock Station" and primarily airs artists who are signed to independent labels. The channel frequently plays songs from an artist's full album instead of just the singles. The Wall Street Journal has described XMU as "XM's alternative-music channel".
From July 15 to July 25 of 2020, XMU temporarily became the Beastie Boys Channel as one of many limited-run stations devoted to a specific artist.

Why this record matters
A short description can identify a subject without explaining its stakes. For “SiriusXMU”, the useful work is to connect “radio station” to the records capable of establishing context and consequence.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q7530398. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2008, 2011, 2010 and 2020.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
