While I know how to download a song, I would like some further assistance. I'll detail them below. Thanks
1. What exactly do the menus mean? EG: #, ?, licence etc. Some are self explanitory, but just some more about them would be good.
2. I would like to listen to a song before I download it. Is this possible? I click on the player at the bottom right but nothing happens. It's definately enabled, but not working?
3. I want to burn songs to a cd for the car. I know limewire does not do this. What version should I download to do this? I obviously need to convert them from mp3 I think? They play on the computer but not in the car. Or is there a particular one to download that will play in the car?
4. What ones should I be looking for to download that will be the best quality?
I think that's all for now. Many thanks.

Sound files (SND) are almost always spam nowadays. File Extension .SND Details That format is usually used for audio sampling, so are just small audio sounds, not actual songs. It would be worth putting .snd into your keyword filter or extensions filter, depending on which version of LW you are using. Here's some more terms you may wish to add included with some good tips: How to find music (point 2 discusses keyword filter)

File Extension .AU Details .AU ... likewise, perhaps add to file extension filter or keyword filter depending whether you are using LW 4 or 5.

AIFF, WAV are lossless (lossless means no loss in quality) uncompressed audio formats identical to CD quality. FLAC, Apple Lossless, APE/Monkey are compressed but lossless quality formats also identical to CD quality but usually between 45-65% the size of wav/aif files.

Then there's the lossy formats that throw away information in order to reduce in file size & are usually between 10-30% of wav/aif file size depending on the bitrate they were converted to. This includes, mp3, mp3pro (which also uses .mp3 extension), aac or mp4 audio which will either use m4a or mp4 file extensions, ogg vorbis (.ogg), wma (not a good format to use), real.

Bitrates? WAV/WAV bitrates are 1600 kbps. Apple Lossless (m4a that are above 320 kbps) & FLAC will be somewhere between 600 to 1200 kbps.

Lossy audio formats such as mp3 & mp4/aac use bitrate compression between 4 up to 320 kbps. Whilst 128 kbps can sound reasonable, usually best to aim for 192 or above up to 320 kbps.
128, 160, 192, 224, 256 & 320 kbps are CBR (constant bit rate.)

There is also variable bitrate (VBR), which is arguably much better than CBR. Example a few seconds silence does not need to be using high bitrate, VBR would encode that passage using a low bitrate. Likewise, some sounds are easily compressed at lower bitrates, whereas some other complex sounds need the higher bitrates, so a song converted using VBR will have its bitrate varying between high & low.
iTunes uses a special kind of VBR. Example, you set 224 kbps VBR & 224 kbps will be the minimum bitrate the song uses & where the sounds need higher bitrate it gives it more, so the highest bitrate for a song encoded at 224 vbr might be 268 kbps which is what the file will show. VBR shows the highest bitrate the song uses.

LW's 'Type' column shows the file extension. The ? column shows the file type icon. This icon will vary from user to user depending on their default program to open such files.

License column will show if the audio file has a license requirement. There is almost no point in downloading such files. These files have generally been purchased over the internet & can only be played by the person who purchased them so should not be shared.

I do show a license column to let me see if audio files in search results have this. However, I disable the other option, see more here License requirement (click on link)

Oops forgot your other questions.

2. Not possible. Can only preview as much as have downloaded. And usually need minimum 5-10% downloaded before can preview. eg: 10% of a 4 min (240 second) song will be around 15-20 seconds of preview. Keep in mind LW does not download a file in sequential order, but might download part of the beginning, part of middle, part of the end. Also keep in mind that when you preview an audio or video file, it creates a preview file inside the incomplete folder called PREVIEW - 38929892 - filename

3. Majority of players in cars can only play standard audio CD's, not mp3 CD disks. You need to choose audio CD format in your burner program, ensuring it does not say mp3 format. Also burn at minimum speed it allows. Choose a good reliable brand of CD-R, do not use CD-RW. I usually use 4-16 speed disks, I stay away from the super speed 40-50 speed capable CD-R's, as burning audio or video at high speeds increases chances of problems. It also means the disk will likely last for a lesser period of time. There's lots of tips here about burning a CD: http://www.gnutellaforums.com/tips-t...ps-tricks.html

After downloading files, try using [url=http://www.videolan.org/vlc/]VLC player. Although VLC is fundamentally a video player, it will also play all audio formats you find on the gnutella network. So if VLC cannot play the file, chances are the file is a fake or corrupt.

More about fake/corrupt files: learn to recognise these file sizes -> WARNING: Viruses on network you should be aware of! (click on blue link). And also see mp3 Bit-Rates Versus File Sizes (click on link) about other types of deliberately corrupted files. Both these things take some time to learn analyzing your search results & recognising what is good & what is not.

Oh just realised you are a Linux user. Linux helpers are few & far between at these forums nowadays which is a major pity. That's most likely why nobody responded to your thread seeing it posted in the Linux section.
