Besides "Trouble" and "Go Insane", why does Lindsey...

[Macfan4life]

I think the answer is simple. These 2 songs are his only solo Billboard hits. Trouble peaked at #9 and Go Insane #23. Lindsey will always promote his new album but plays the hits from his first 2 albums. Of course there are fantastic songs on those albums especially Go Insane. Lindsey has a wealth of solo songs.
He is obvious very proud of those songs just like he is of So Afraid ( a song he does every Mac tour) and Tusk.
You could ask lots of questions like these like Why does Lindsey only play Big Love from Tango and not any other Tango song.
Why did he and does he not play any of his songs from Mirage.
You could go on and on
