Hi, how can i get the size of the music file (minutes) before donwloading it?

Also when I write title,singerand album I always get the message of "search being to specific" how come?

If you hover your mouse pointer over the song (& it has had an id tag added) then it will normally specify the length of the song.

Try doing a general type search (AnyType), if you're having those problems. ie: artist - song title

Then in your search results, use the filters: click on audio, artist & album.
