'Lift Me Up' is a great song, but my review is more for the b-side 'Mulholland'.
Now, it's an ok song, but just that: ok. It's a nearly 9-minute affair of down tempo electronica. If you've seen Moby's 18 DVD, where he shows you his studio and takes you through the making of a song, it's sort of like that. This track sounds like it was put together in about half an hour. It may sound shallow of me, but I would've loved to hear some 'Hotel' b-sides with vocals; he just seems to put more effort into them. For casual fans, this two track business is not for you; I would recommend though, if you really want this b-side, to download it independently of the single track, being as it is no different from the album version.
And how come we didn't get to hear a b-side album for 'Hotel'? I know it's not a prerequisite for Mr. Moby to make one for us for every album, but I think it is owed to us for the ungodly amount of singles this album produced (nearly every song on the album has made one, or four, different single releases).
