You want to adjust the recording to fit a fixed tempo, and that means using elastic audio and manual work.

The basic procedure that I use at least goes like this:

- Find the appx. tempo of the track by playing it, click on the tempo field in transport window, and tapping 'T' key. You'll see the tempo value will change to match your tapping.

- Find a good bar one in the track and place it on the grid on, say bar five. turn on the metronome and the tempo should match for a few beats until the recording starts to drift.

- Turn on elastic audio polyphonic and set the track to ticks instead of samples.

- Set the track to warp view.

- Place a warp marker on your bar one.

- Find, say bar one of verse two, and place a warp marker there too. If it's not on the grid line, drag it there.

- Find bar one of verse three, place warp marker and line it up to the grid.

Repeat until the end of the song, and you will have the audio roughly adjusted to match the grid and the tempo you chose in step one.

Play the track and the click, and insert more markers and fine tune it until you're happy with the song matching the click.

At least this is how I do it.

Oh, and here's a lot of tutorials on this on youtube.

That’s some awesome advice! Thanks!
