...Something to Be is the debut solo album from the Matchbox Twenty lead singer Rob Thomas. The album was released on April 19, 2005, and it debuted at No. 1 on the US Billboard 200 albums chart, knocking out Mariah Carey's The Emancipation of Mimi. The album spawned the US top ten hit "Lonely No More". It also features John Mayer's guitar on the single "Streetcorner Symphony".[6] The album was released in the DualDisc format, the first major album to be released that way. The album itself is certified Double Platinum by the RIAA in the US[7] and consists of several types of sounds, including dance, pop, Latin, rock, and country, although it can be generally classified as closer to pop than to the rock music of Matchbox Twenty's third studio album, More Than You Think You Are. The album was supported by his 2005–2006 Something to Be Tour.
