I don't know if this is the intended behavior or a bug.

When selecting a few folders from the album list and drag the to create a playlist tab, foobar2000 creates really long playlist name.
One example, I selected 17 folders from the album list and dragged them to create a new playlist tab, the playlist tab was called:

"Anne Grete Preus - 1988 - Fullmåne [242 296-2]; Christine Sandtorv - Stjerneteller - Gullamanter [FEM 304]; Folk & Røvere Feat. Ravi - Utadæsjælåpplevelse [VOW080]; Ida Maria - 2008 - Fortress Around My Heart [602517693647]; Joakim Gunnerød - Antisjekker'n EP; Kristin Asbjørnsen - 2009 - The Night Shines Like The Day; Madrugada; Odd Børretzen, Lars Martin Myhre - Syv Sørgelige Sanger Og Tre Triste [BBRCD 020]; Rita Eriksen & Dolores Keane - Tideland [FXCD 175]; Roy & Rypejegerne - 1992 - Det Driter Jeg I [RR002]; Silje Karlsen - 2006 - Pearls In The Trees; Silje Karlsen - 2007 - Sundays And Raindays EP; Tramps, The - Silver & Gold [T1]; VA - Mormor Og De Åtte Ungene (Musikken Fra Anne-Cath. Vestlys) [PARADOX001]; VA - NRK P3 Presenterer- Rørt Og Urørt 2006 [WTRP3-03]; VA - Vi Ønsker Deg En Riktig God Jul Og Godt Nytt År [DK 24891]; Øystein Sunde - 1989 - Kjekt Å Ha [GTXCD 2011]"

This behavior is present in foobar2000 v1.6.5 and 1.6.6 b7.

Using Win10 Pro x64 (20H2) Build 19042.985

Oldest version around on my drive right now is 1.3.15, and it does the same.

Thanks Porcus. I guess it's not bug then. Just my memory not being that good.
