As previously posted lead free is almost imperative for video and digital repairs and construction, If used for analogue , it can sound a bit too bright.

Bismuth solder has ultra low melting point below 200 degree F IIRC. This is marketed by Sony as an SMD chip removal solder, Add some of this solder to the legs of an IC and then you can literally flick away the chip with a paint brush, the melting point is so low and it literally floats the chip right off the board.

Interestingly, the best sounding solder I have found is the AQ solder. No word on the composition but it is advertised as having more silver than lead. Since most solders have a maximum of 4% silver in order to achieve reasonable working temperatures the lead component must be lower than that. Solder flows easy, looks like a lead free when cooled ( in other words like a cold solder joint), Bass is very solid and the top end is very good but not bright.The small amount of lead enables it to flow very easily too.
