Note that i only mention the differences between them.

Spotify

Good:

1. It`s fast to start!
2. Streaming starts fast!
3. You can create lists that will work when offline
4. Does not have any journalists to pick out nice songs and kinda create a community around that
5. It`s free – So you can test it better before paying for it

Bad:

1. They are starting to loose music due to bad payments to producers etc
2. Not too much Norwegian music (for those who care )

Wimp

Good:

1. You can see others play list easier than in Spotify (at least the most popular)
2. The design is more white-ish than Spotify
3. Easy to see the play queue and what have been played
4. Easier access to songs/albums within a genre

Bad:

1. No free version, although you get the first 30 days free
2. No offline ability, d`oh!
3. I cannot set my own password, why?
4. Its only in Norwegian for now, and it requires a Norwegian cellphone(?)
5. When i forget the generated password, i get the same password sent to me..so long for security
6. It uses a lot more resources (10 times the RAM of Spotify…)
7. Due to #6, it is very slow on some machines
8. The “change password” link in the program sends me to a page without ability to change password
9. On one of my computers, i cannot restore the program when sending it to the tray bar..whoops

In conclution

I will keep to Spotify for as long as they have enough music, or until Wimp fixes some of the most annoying things.
