I hope http://music.google.com (I was in after one week from hitting that page up).

I have no Bitcoin to spare, if no one takes you up on the Spotify invite, I will gladly take one and check it out to the fullest (I don't work for Google, but I have used a lot of players in my life, and this is 'the one' so far).

Note: Apologies if you are doing viral work for Spotify or work for them, I do not mean to advertise competition, but I'm sure both have many great exclusive things to offer depending on the users tastes.

Spotify is a legal and convenient way of playing music, as well as sampling new music. The free version is limited, since it's only 160 kbs. Paid is 320. However most people would consider 160 enough, to sample new music, since it's instant, at the click of a mouse button. Anyway, it's better than youtube's 96-128 kbs and lower, plus it's faster. Many people also use spotify for regular listening, cause it's cheap and easy to use.

Myself I torrent all my music these days, for delicious FLAC quality. So I cancelled my paid membership, since I do not use it. However not all people bother to gather 513 gigabytes of music, as I have (just checked). Nevertheless I find myself using free spotify, to check out new music in a fast and easy way. It is also popular among my friends and it's a nice way to share music with each other. You can also see the shared playlists of your facebookfriends, currently it seems like 90 of my 209 facebookfriends have Spotify.

So to summarize, I use it cause it's a fast way to sample new music. Some people also use it cause it's easy and legal.

(if you can get in the beta).

I have over 13,000 tracks in my Google Music account.  That is hooked up to my Android (free) and even plays tracks offline.   How can Spotify better this?
