playback speed for hearing impaired

[hejb]

For some people with hearing aids, music that contains rapid-fire lyrics can sound mushy - the words blend together and become indistinguishable.  Is there a way to slow down the playback in Spotify?  Am I not seeing the control for playback speed, or is it not there?

Actually, a feature that allows adjustment of playback speed would help people in other situations, too.

Any advice would be appreciated.
