Slow Playback

I searched the forum’s and didn’t find what I want… So i’m sorry if I missed it.
Basically I am trying to match the beat of two covers of a song for the fun of it. The marching band version and the original version’s bass and reverb is making it hard to match it at normal speed. I slowed down (tempo change) both covers to a point where i was able to fix it- but when i sped it back to normal speed the sound was very distorted. What i would now like to ask is if there is a way to playback the audio slowly… without the program editing the songs.
I am bad with my words… so I apologize if what I am asking makes no sense.

Does the Transcription Toolbar do what you want?
