you're welcome, onemug. a few parting rants, then i'll leave this subject alone:
1. i still mourn mog's demise, but all good things must pass...
2. compared to mog, spotify may have a better library--it has some artists (led zep, aimee mann) who were conspicuously missing from mog, altho it also omits some of the alternative/obscuro stuff i found on mog.
3. spotify's "discover" feature, which recommends artists based on your previous selections, works very well and is updated more frequently than was mog's.
4. likewise, spotify seems to post new releases more quickly than mog.
5. spotify's customizable radio mode is ok, but not as cool or easy to use as mog's "mobius technology" (which let you select how much of a particular artist you want to hear by moving the contiuum slider, and thereby tailors the radio station much more precisely to what you want to hear).
5. spotify's offline mode is decidely inferior to mog's--it's easy to download music for offline listening but difficult to find specific artists or tracks you downloaded.
6. the big advantage of mog was its interface, which was extremely intuitive and easy on the eyes. even after a month or so i find spotify's interface difficult and confusing--it often requires scrolling through different menus, and most maddeningly, presents everything against an almost unreadable black background, which is difficult for me to see, let alone navigate.
