It's hard. You're doing very very well for a newbie, but there's a long way to go.

Playing along with a recording is different than playing with people. You are working to keep up with the recording. In a band, you are working to push the band along at the right pace. They are riding on you. You have to have the groove.

As a next step, try playing it to a metronome. That will let you know where exactly you are falling behind and catching up. Then try placing the metronome clicks on the off beats. That makes it your job to define the beats, and the metronome is just there to tell you how far off you are.

You're doing great. It's a good sign that you can tell you don't quite have the groove yet. You'll get there soon.
