How to make Spotify better

I have been a fan of Last.fm for a while now.  I do not care for Pandora, however.  Pandora seems to be VERY random and put a lot of strange things on my list.  Why am I hearing Rhianna on a list of 80's music?  Why is Beyonce on my Less Than Jake station?!  It makes no sense.  I feel like Last.fm leanrs my listening habits much better and is able to give me music more focused at what I am looking for.  Last.fm always pays attention to what I've listened to and can play back those songs as well.  ALL OF THEM.  Well, anything that they have the appropriate rights to.

I have switched to Spotify for a little bit now.  My brother seems to like it and a lot of people are on the bandwagon.  It isn't bad, but it isn't all that good, either.  I have compiled a list of things that I would like to see added that would make it more well-rounded and worth of it's 10 dollar a month fee.

1. Love/hate, upvote/downvote.

2. More variation based on selected radio.

3. More easily manageable playlists (online/offline).

4. Support for MORE artists.

I have used Spotify for many things, but one of the things that I really wanted to do was find artists similar to those I already enjoyed.  It is very hard to find good music these days and Spotify doesn't make it any easier.  On top of the mediocre radio (which is supposed to lump like groups together), it moves further away from band similarities and almost becomes hilarious in some situations.  The "New" and "Popular" songs and albums are hilarious.  I was hoping that a music provider with such a huge tie to social media would at least understand what I enjoyed.  It doesn't.

If they could somehow find a way to implement Last.fm type features into this, I'd buy it 100%.  It isn't all bad, but it's bad enough that I can't help but wait for improvements.  If those don't come, I'll be ditching this service.  I just hope others are smart enough to do the same.
