completely useless. It seems as just a way to add DRM and gain more control over the music.
things like news updates with the music is crap, because when music services have "news updates" it usually means advertisement in the form of a news update
lyrics are useless also, many players will automatically get them and most people don't like reading them anyway.
this will only add more to the file size while offering no additional quality. it will also be a problem for users with limited bandwidth, imagine a collection of like 15000 songs trying to update them self every little while, it will be a waste of system resources and also a waste of bandwidth.
while there are better formats out there, unless you have a $500-1000 pair of headphones you generally cant tell the difference.
when going from a 320k mp3 to flac, generally all you get is a slight improvement in the treble and it is hard to notice in many cases.
if they want to reduce piracy, adding advertisements and DRM wont help, what they need to do is offer better service. allow people to sample like half of a song minimum or the entire thing (eg with pandora radio, I bought a lot of music because I was able to hear the whole song and since I liked the whole song, a simple click of the buy button is enough for me to get a legit copy of a song in good quality)
they also need to reduce music prices, especially when it is digital, sending someone 10MB of data is insanely cheap generally about 1/1000 of a penny
if music was priced like 5-20 cents per song, more people will buy the music because it will be safer and cost effective, and they can still make a good profit from it
when music is sole online, it is pretty much 100% profit
with digital, other than the initial production, all other sales ate basically 100% profit.
