Just upload a song from the internet http://t1.gstatic.com/images?q=tbn:ANd9GcQ6AoB__PgAPil1xRYP-B2Fq_qPnsa7u8UffnnCH8NPW_huH4_Vnw

whenever I do what every one is telling me to do this block wont work!

when I try to upload it says instance and a bunch of other numbers, and the song is not there

Excuse me can you please tell me first of all how to download music on your file. Sorry if it is a stupid question but I'm only 9 almost ten years old!

Chose the video you want from youtube and copy the url go to youtube to mp3 converter paste the url then click convert then click download in the blue
then go to media/io click select files to upload look for your song in downloads click the wav files and click it and once again look for your song in the downloads then click download then go to the sound selection on scratch create mode and look for the upload song from downloads button and click it then click this

I can't do sound witch effects. When I doing this my music or sound is really bad…

I'm sorry I don't know why it's doing that?

I dont understand the whole thing

Don't understand what?
Oh

Oh right it's a lot to grasp!
just go to this URL,scratch.mit.edu/projects/24103877/
and it all will make sense to you!

I still dont understand!

Really!?
did you do what she told you to do?
'cause if you did not it would mess up the whole thing!?!?
how does it not make sense by the way?

Make sure you use .WAV files when uploading sounds. In order to upload music, you must first have the music on your computer (if you are uploading custom music). When you click the last tab on a background or a sprite, click the button that says “Upload from Directory” or something similar. Then, go to the folder (or directory) your music is in. Click open, and depending on file type and size the uploading speed varies.
I said to use .WAV because it uploads much faster, plus it won't crash your computer (like mine once did).

Hey I agree with you!!!!! I'll ask someone then that knows all about scratch!!!!

This thread made me facepalm,
its so simple, all you do is:

1) download a song (off any website)
2) Open your scratch project
3) Click “stage” on the bottom left of the screen
4) Click the “sounds” tab up near the top
5) Press the folder icon directly underneath were it sais “new sound”
6) select the file you downloaded in step 1
7) press “open”
8) click the “Scripts” tab up near the top
9) Put in the following code:

10) Your done!

or u can put songs in your backpack its at the bottom! =3 and when u go to sounds to another persons animation or somthing and if u like the song just find it and drag it in your Backpack!

Hope i helped

yea use youtube mp3

Go to the sounds tab
Click that folder thing.
Find your song.
Then do this:

Boom.

Where to get music? Download it somewhere.

Hope I helped!

I finally decided to address this issue by doing a thorough guide about this.
(Im using Ubuntu Linux, Chromium 40.0.2214.111, Flash 16.0 (release 0)

Issues
-Sometimes MP3 Files dont work, thats why you have to convert them to .wav (which causes the music quality lower down significantly, well just because .wav sucks. = Use: MP3 TO WAV


Now, lets get to the actual guide

This should be your default. There is no code, but you can fix that by going to the “Sound” page and choosing “play sound - until done” or “play sound -”
Which then looks like this.,.


After you're done with that, press the dropdown arrow, and it should show up like this.


After that, press “record…”

You can choose from these three:
Upload sound from library

or record a new sound

or just take one from your computer


After all of this, choose your music from the dropdown menu that i showed you earlier!


Now just make your own code.
