I often browse my playlist and would love to be able to just quickly press something like the Q key to add the selected song(s) to the queue. Now I have to use my mouse again and it gets pretty annoying to quickly add songs to the playqueue.
Would love to have it more work like it did in programs like WinAmp. There you could just press Q to add the song to the queue, select multiple songs and in the playlist queue you could easily rearrange the songs. Now in Spotify it's a little harder to perform these things.
