I have record music with singing along with the music with one record but with another record just the music and not the singing and yet I can’t understand why. I do hear the music but when I record it just the music comes through and not the singing
Make sure you’ve selected your microphone as the [u]Recording Device[/u].

Mixing Narration With Background Music
I mean with a LP or Albuml
You mean you’re singing to a live vinyl playback? Are you going through a mixer or other multi-channel interface? If not, then Audacity is going to get you or the music, not both. Audacity can’t deal with more than one source.
If I missed that, then it could be how you connected the two players. If you did it wrong, one of them isn’t stereo, it’s badly mixed mono and it’s possible the main singers cancelled out.
So how did you do it?

No No No You guys don’t get it. I record with a Album with singing to it. I did it with one record and it did fine but with this one it doesn’t record the singing part just the music and I DONT MEAN WITH A MICROPHONE OR PUTTING IN THE WRONG CABLES!!!
OK… Please tell us about your hardware setup and how you’re connected to the computer. Do you have a USB turntable with a USB connection to the computer? Do you have a stereo system with “tape outputs” connected to line-in (blue) on your soundcard? Etc?
Do you have a laptop computer (with only mic-in and headphone-out) or a desktop with a “regular soundcard”?
Are you using an external audio interface or any other hardware?
Can you hear the vocals when you play the record while recording (through the computer or through your stereo system)?
We may have some more questions but that should get us started.
Somehow… The left & right channels are getting subtracted. This can happen with mis-wiring.* This is how the vocal removal effect works, but it subtracts digitally and intentionally. Subtraction removes everything in the center (everything that’s identical in both channels) which means usually the vocals, bass, and any lead instruments also get subtracted-out.

- You may actually have two problems… A mis-wired phono cartridge (with one channel inverted) and a mono connection to the computer If one channel is inverted and you mix to mono, you’ve got subtraction.
I am using Windows 10 Pro on a desktop with a USB cord into a Turntable port. I am using the speakers that came with the Turntable which has very good sound. I hear the sound from the speakers which I am recording. When the song finshing playing I then play back the song that has been recorded I hear mostly the music and bearly the singing. But when I do the same thing on a different LP I hear the music and the singing. That is weird I know Cause I back track on other recording and I hear the music and the singing.
That’s very strange… It’s not “easy” to mess-up the digital USB data, and Audacity only “captures” what it gets from the drivers.
What’s the make & model of the turntable?

The “bad” record has vocals in the center, right? …err …I mean correct? On some early Beatles records the vocals were only on the left or right, and if you were to loose that channel and accidently record in mono, you’d obviously loose the vocals. And a regular-mono file will play-back through both speakers so you might not notice it’s mono.
Does Audacity show you two waveforms (left on top and right on the bottom)? If you’re only getting one waveform, make sure the device toolbar shows “USB… something” and make sure it’s set for 2-channel stereo.
If you do have two waveforms, try running the Vocal Remover effect (leave the default settings). This won’t “help”, but it may give us a clue - If you get silence (flat lines) the left & right channels are identical (sometimes called “dual-mono”). If it gets louder and the waves get bigger, the left & right channels are out-of-phase (one side is inverted).
I assume your turntable has [u]RCA connectors[/u] or a headphone output? If you have a good analog signal you can record that. Try connecting one of those outputs to line-in on your soundcard (usually blue). Then of course, select line-in as your recording device.
I am not sure if I have done this right about removing the voice remover effect. I hit the Ctrl -A and both lines of sound still came through even though I still hear the singing very faint. I am thinking that is the bad recording of this record I have no problem with other records but only this one. But still I would love to know if any problems be fixed.
By the way at the top I see both L and R lines is working even though I only hear the music playing and not the singing.
…Have you considered buying the CDs or MP3s? 
Can you [u]attach a short WAV or MP3[/u] that includes part of the song where the vocal was killed? There are file size limits, so you can post a longer sample if you make an MP3, but if you haven’t made an MP3 with Audacity before, WAV is easier.

If both channels are identical the Vocal Removal will give you total silence. So it appears both sides are working and I don’t know how the vocals are getting lost… And, Vocal Removal will make both sides the same, so if you run it twice you should get silence.
Did you try the vocal removal effect on the one with missing vocals? That might tell us something.

You said it’s OK when you play the just record through the speakers so something is going wrong during recording, and the other records may be affected in some way that you haven’t noticed yet. 
When you play the “problem record” through the speakers, are the vocals coming-out of both speakers (i.e. “centered”)?
P.S…
I wonder if your digital recording is OK, but there’s something “unusual” about your computer playback??? For example, we’ve seen recordings that play OK (in stereo) on a computer, but loose vocals when played back in mono through a smart phone speaker (because the vocals are out-of-phase).
What record is this (artist/album)? Do you know what year it’s from? Does the record jacket say something like “artificially enhanced stereo” or something like that?
If you have another computer handy, try playing the file (MP3, WAV, etc.) on the other computer to see if the vocals “come back”. Or if you’re planning on making CDs, go-ahead and burn the CD and try it on your CD player. Or if you want to try the MP3/WAV on your phone, try it with (stereo) headphones/earphones.
