Better auto suggestions

[GregSherman]

Right now, the auto suggestions just take the last 5 played songs. For a user to change the genre of the station, they have to fight AL and play 5 songs.

The auto suggestions should instead be based on user suggestions within the last 5 songs only, if there are none then just use the last 5.

Further optimizations can be made by trying to take the majority genre of the last 5 suggested songs, but Spotify has many niche genres that are within the same subgenre.
